make-pgtap-tests.pl

For seeding a baseline set of pgTAP tests for Evergreen.  By default, assumes
PostgreSQL is running on localhost at port 5432 with a database name of
"evergreen", and with an "evergreen" user configured with password "evergreen".

Command-line options for tweaking these are

    -db_name=? -db_host=? -db_port=? -db_user=? -db_pw=?

Make sure to install pgTAP (probably best do it from source for all the
assertion functions we're using) for the database you want to run the tests
against.

I did the following for my test environment:

    git clone git://github.com/theory/pgtap.git
    cd pgtap
    make
    make installcheck
    sudo make install

Then in my Evergreen database with psql, I did:

    CREATE EXTENSION pgtap;

I also installed a CPAN module to get pg_prove:

    sudo cpan TAP::Parser::SourceHandler::pgTAP
