pgsql: CREATE DATABASE cannot be executed from a function or multi-command string

This is a "pre-emptive" bug report.

Newer version of Postgres have changed the ability to send a CREATE
DATABASE function in a block with other statements.

I noticed this error message when running gnue-schema --createdb,
something that gnue-setupdb uses.

Looks like line 122 needs to change.
