Testing

Testing this package is extra tricky, because you need a working PostgreSQL server.

The test suite in this package is supposed to auto-spawn one, but that consistently fails at present.

Portage Configuration

Instead, you need to set one up manually.

FILE /etc/portage/env/pgtest.conf

<syntaxhighlight lang="bash">
#!/bin/bash
# Important: You want to skip hostname and port
# here if you need to use unix sockets
# eg: under FEATURES="network-sandbox"
DBI_DSN="dbi:Pg:dbname=pgtest"
DBI_USER="pgtest_user"
DBI_PASS="test"
# Uncomment this if you have problems working out why its skipping
# DBDPG_DEBUG=1
</syntaxhighlight>

FILE /etc/portage/package.env/pgdb.conf

dev-perl/DBD-Pg pgtest.conf

Database Configuration

Then, you must setup the named account, database, and permissions as follows via psql -U postgres

CODE schema

<syntaxhighlight lang="sql">
CREATE ROLE pgtest_user LOGIN PASSWORD 'test' VALID UNTIL 'infinity';
CREATE DATABASE pgtest
  WITH OWNER = pgtest_user
       ENCODING = 'UTF8';
GRANT ALL ON DATABASE pgtest TO pgtest_user;
</syntaxhighlight>

Test Output

If you see output like this:

CODE

t/01connect.t ....... Please wait, creating new database (version 9.6) for testing

All tests successful.

Then your configuration has failed and you have not passed any meaningful tests, and you should probably employ DBDPG_DEBUG=1 to see what is breaking your connection attempts.
