Question

I am getting this error message (shown in title), when I run this SQL statement in PG 8.4:

psql -h localhost -U postgres -d mydb -c "CREATE TRUSTED PROCEDURAL LANGUAGE 'plpgsql' HANDLER plpgsql_call_handler VALIDATOR plpgsql_validator"

What’s causing this (it used to work with earlier versions of PG), and how do I resolve it?

Answer 1

This procedure has been simplified. For plpgsql simply use:

CREATE LANGUAGE plpgsql;

The error message tells you, that plpgsql is among a number of predefined languages listed in the system table pg_pltemplate. Just have a look:

SELECT * FROM pg_pltemplate;

In PostgreSQL 9.0 and later, PL/pgSQL is pre-installed by default.
