I have written a patch to issue an hint if someone tries to create a
function in a language that isn't loaded into the database:
test=> CREATE FUNCTION xx() RETURNS INT AS '
test'> select 1'
test-> LANGUAGE 'plpgsql';
ERROR: language "plpgsql" does not exist
HINT: Perhaps you need to use 'createlang' to load the language into
the database.
I know Peter didn't like this idea in the past, but we are getting too
many people who forget createlang, and with our new HINT tags, it seems
appropriate.
