Re: pg_agent jobs

Hi, Yes I know I've to use the "on error" property, but the cue is to raise
an error if query has a false result: for my knowledges the only way to do
it is to "create or replace" a PL/pgSQL procedure that than uses a "RAISE
ERROR" inside, but isn't there a more "SQL only way to do it?
thanks in advance, G
