### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

---

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.

  <title>Description</title>

  <para>
   <command>CREATE LANGUAGE</command> registers a new
   procedural language with a <productname>PostgreSQL</productname>
   database.  Subsequently, functions and trigger procedures can be
   defined in this new language.
  </para>

  <para>
   <command>CREATE LANGUAGE</command> effectively associates the
   language name with handler function(s) that are responsible for executing
   functions written in the language.  Refer to <xref linkend="plhandler">
   for more information about language handlers.
  </para>

  <para>
   There are two forms of the <command>CREATE LANGUAGE</command> command.
   In the first form, the user supplies just the name of the desired
   language, and the <productname>PostgreSQL</productname> server consults
   the <link linkend="catalog-pg-pltemplate"><structname>pg_pltemplate</structname></link>
   system catalog to determine the correct parameters.  In the second form,
   the user supplies the language parameters along with the language name.
   The second form can be used to create a language that is not defined in
   <structname>pg_pltemplate</>, but this approach is considered obsolescent.
  </para>

  <para>
   When the server finds an entry in the <structname>pg_pltemplate</> catalog
   for the given language name, it will use the catalog data even if the
   command includes language parameters.  This behavior simplifies loading of
   old dump files, which are likely to contain out-of-date information
   about language support functions.
  </para>

  <para>
   Ordinarily, the user must have the
   <productname>PostgreSQL</productname> superuser privilege to
   register a new language.  However, the owner of a database can register
   a new language within that database if the language is listed in
   the <structname>pg_pltemplate</structname> catalog and is marked
   as allowed to be created by database owners (<structfield>tmpldbacreate</>
   is true).  The default is that trusted languages can be created
   by database owners, but this can be adjusted by superusers by modifying
   the contents of <structname>pg_pltemplate</structname>.
   The creator of a language becomes its owner and can later
   drop it, rename it, or assign it to a new owner.
  </para>

  <para>
   <command>CREATE OR REPLACE LANGUAGE</command> will either create a
   new language, or replace an existing definition.  If the language
   already exists, its parameters are updated according to the values
   specified or taken from <structname>pg_pltemplate</structname>,
   but the language's ownership and permissions settings do not change,
   and any existing functions written in the language are assumed to still
   be valid.  In addition to the normal privilege requirements for creating
   a language, the user must be superuser or owner of the existing language.
   The <literal>REPLACE</> case is mainly meant to be used to
   ensure that the language exists.  If the language has a
   <structname>pg_pltemplate</structname> entry then <literal>REPLACE</>
   will not actually change anything about an existing definition, except in
   the unusual case where the <structname>pg_pltemplate</structname> entry
   has been modified since the language was created.

       the name of a previously registered function that will be

       handler for a procedural language must be written in a compiled
       language such as C with version 1 call convention and
       registered with <productname>PostgreSQL</productname> as a
       function taking no arguments and returning the
       <type>language_handler</type> type, a placeholder type that is

       in this language.
       If no <replaceable class="parameter">inline_handler</replaceable>
       function is specified, the language does not support anonymous code
       blocks.
       The handler function must take one argument of
       type <type>internal</type>, which will be the <command>DO</> command's
       internal representation, and it will typically return
       <type>void</>.  The return value of the handler is ignored.

       when a new function in the language is created, to validate the
       new function.
       If no
       validator function is specified, then a new function will not
       be checked when it is created.
       The validator function must take one argument of
       type <type>oid</type>, which will be the OID of the
       to-be-created function, and will typically return <type>void</>.
      </para>

      <para>
       A validator function would typically inspect the function body
       for syntactical correctness, but it can also look at other
       properties of the function, for example if the language cannot
       handle certain argument types.  To signal an error, the

  <para>
   The <xref linkend="app-createlang"> program is a simple wrapper around
   the <command>CREATE LANGUAGE</> command.  It eases
   installation of procedural languages from the shell command line.
  </para>

  <para>
   Use <xref linkend="sql-droplanguage">, or better yet the <xref
   linkend="app-droplang"> program, to drop procedural languages.
  </para>

  <para>
   The system catalog <classname>pg_language</classname> (see <xref
   linkend="catalog-pg-language">) records information about the
   currently installed languages.  Also, <command>createlang</command>
   has an option to list the installed languages.
  </para>

  <para>
   To create functions in a procedural language, a user must have the
   <literal>USAGE</literal> privilege for the language.  By default,
   <literal>USAGE</> is granted to <literal>PUBLIC</> (i.e., everyone)
   for trusted languages.  This can be revoked if desired.
  </para>

  <para>
   Procedural languages are local to individual databases.
   However, a language can be installed into the <literal>template1</literal>
   database, which will cause it to be available automatically in
   all subsequently-created databases.
  </para>

  <para>
   The call handler function, the inline handler function (if any),
   and the validator function (if any)
   must already exist if the server does not have an entry for the language
   in <structname>pg_pltemplate</>.  But when there is an entry,
   the functions need not already exist;
   they will be automatically defined if not present in the database.
   (This might result in <command>CREATE LANGUAGE</> failing, if the
   shared library that implements the language is not available in
   the installation.)
  </para>

  <para>
   In <productname>PostgreSQL</productname> versions before 7.3, it was
   necessary to declare handler functions as returning the placeholder
   type <type>opaque</>, rather than <type>language_handler</>.
   To support loading
   of old dump files, <command>CREATE LANGUAGE</> will accept a function
   declared as returning <type>opaque</>, but it will issue a notice and
   change the function's declared return type to <type>language_handler</>.
