Efficient min/max over partitioned table

PostgreSQL 9.0 and earlier don't support indexed MIN(x) or MAX(x) queries over partitioned/inherited tables. See MAX Partitioning with MIN Pain for a test case showing the problem, and how it is resolved starting in PostgreSQL 9.1. However, it's possible to do this efficiently in earlier versions with a custom PL/pgSQL function.
This snippet was contributed by Shaun Thomas on the pgsql-performance mailing list, then tweaked with feedback from others. The original version of the function presented there worked with PostgreSQL 8.2, and may be necessary for users on that version. The simplified version here is only compatible with PostgreSQL 8.3 and later due to its use of regclass features introduced in that version.
This function works with bigint (and integer/smallint) columns and uses the MAX() aggregate. It shouldn't be difficult to port this to other datatypes or make it work with min().
== Function definition ==
/**
* Return the Maximum bigint Value for a Partitioned Table Column
*
* @param string Name of table, may be schema-qualified.
* @param string Name of column to search.
*/
CREATE OR REPLACE FUNCTION spc_max_part_int(rParent regclass, sColName text)
RETURNS bigint AS
$$
DECLARE
 rChild regclass;
 nMax bigint;
 nTemp bigint;
BEGIN
 EXECUTE '
 SELECT max(' || quote_ident(sColName) ||')
 FROM ONLY ' || rParent
 INTO nMax;
 FOR rChild IN
 SELECT inhrelid
 FROM pg_inherits
 WHERE inhparent=rParent
 LOOP
 nTemp := spc_max_part_int(rChild, sColName);
 nMax := greatest(nTemp, nMax);
 END LOOP;
 RETURN nMax;
END;
$$ LANGUAGE plpgsql STABLE;
== Example usage ==
db=> explain select max(foo_id) from foo;

Email address parsing

This function extracts the real name from an email address. With slight variations, other components such as local part or host name can be extracted. Relying on a well-tested Perl module makes this function extremely robust, compared to say handcrafted pattern-matching approaches.
CREATE OR REPLACE FUNCTION email_name(email text) RETURNS text
LANGUAGE plperlu
AS $$
use Email::Address;
my @addresses = Email::Address->parse($_[0]);
return undef unless scalar(@addresses) > 0;
return $addresses[0]->name;
$$;

Encontrando consultas que consumen recursos

== Ubicar que consultas está ejecutando un proceso apache. ==
Hace poco estuve asesorando a un cliente que tenia una serie de problemas de rendimiento. Hice cuanto pude con las configuraciones pero lamentablemente una consulta mal escrita puede dar como resultado un pésimo rendimiento sin importar la máquina o las configuraciones...
El gran problema es que era una aplicación web que fue armada como Frankenstein (con partes de diversos proveedores) y lo peor de todo es que las consultas se generan dinámicamente, lo que hace que darle mantenimiento sea un dolor de cabeza... imaginen tratar de obtener que página está ejecutando que consulta en ese ambiente (si alguien sabe de una solución simple se la agradecería).
Lo que he logrado por ahora es determinar que sentencias ejecuta un determinado proceso apache, con eso pude rastrear hasta determinar porque en ciertos momentos el servidor se colgaba (determinar exactamente que pagina enviaba las consultas ya es otro cuento).
Asi que a lo mejor a ustedes también les sirva:
=== Preparar el log de PostgreSQL para el monitoreo de los procesos apache. ===
Primero debemos modificar unos parámetros en el postgresql.conf:
log_line_prefix = '%r' 
Podemos mantener lo que haya tenido antes el parámetro, solo es necesario añadir el %r. Esto grabará la dirección IP y el puerto de la máquina cliente.
log_statement = all o log_min_duration_statement = un_valor_razonable
Para no llenar demasiado el log con información inútil puede usar 'mod' si usa log_statement o un valor razonable si usa log_min_duration_statement.
=== Escoger el proceso apache que queremos monitorear. ===
Para escoger el proceso apache que queremos monitorear podemos usar el siguiente comando (en el servidor de aplicaciones):
ps aux | grep httpd | awk '{print $2, $6}' | sort -­n -­k 2 
Este comando nos mostrará una lista ordenada de procesos apache, donde la primera columna es el PID del proceso y la segunda columna es la cantidad de memoria que esta consumiendo (la lista sale ordenada por esta columna de menor a mayor).
Escogeremos un proceso que sostenidamente este ocupando mucha memoria.
=== Enlazar el proceso apache con una conexión a la base de datos. ===
Una vez escogido un proceso ejecutamos el siguiente comando (aun en el servidor de aplicaciones):
lsof -­i TCP@$ip_servidor_bbdd | grep $pid_escogido | awk '{print $8}'
Lo cual genera una salida similar a la siguiente (ip_cliente:puerto_cliente­->ip_servidor_bdd:puerto_sevidor_bdd):
webserver.servidorweb.com:55774­>postgresql.servidorpgsql.com:postgres
Usando esos datos podemos buscar en el log de postgres que sentencia SQL fue ejecutada desde esa IP cliente a traves de ese puerto cliente.
grep $ip_cliente $archivo_log | grep $puerto_cliente
NOTA: Al buscar en el archivo de log se debe hacer usando la IP de la máquina cliente y no el nombre en la red.

Enumerated Types

This page describes a design proposal and patch to add enumerated types to PostgreSQL.

Escribir aplicaciones con PostgreSQL

Escribir aplicaciones con PostgreSQL
Por:
Bruce Momjian
PostgreSQL es una bases de datos objeto-relacional desarrollada en Internet por un grupo de desarrolladores en todo el mundo. Se trata de un código fuente abierto alternativo a las bases de datos comerciales como Oracle e Informix. Este artículo discute los conceptos necesarios para escribir aplicaciones que utilizan PostgreSQL. El informe abarca el propósito de las bases de datos y cómo comunicarse con ellas desde las aplicaciones.
PostgreSQL fue desarrollado originalmente en la Universidad de California en Berkeley. En 1996, un grupo comenzó el desarrollo de la base de datos en Internet. Utilizan el correo electrónico para compartir ideas y servidores de archivos para compartir código. PostgreSQL es ahora comparable a las bases de datos comerciales en términos de características, rendimiento y fiabilidad. Posee transacciones, vistas, procedimientos almacenados, y las limitaciones de integridad referencial. Soporta un gran número de interfaces de programación, incluyendo ODBC, Java (JDBC), Tcl / Tk, PHP, Perl y Python. PostgreSQL sigue mejorando a un ritmo tremendo gracias un talentoso grupo de desarrolladores en Internet.
