Re: plpgsql exception handling

when I run 'select 1count(*) from table' in my postgres 8.4 installation, I
get the exact same error message. Assuming the '1count()' function does
exist, perhaps you need to full qualify it with a schema name?

It looks to me like the query you are passing to the procedure is invalid
and is generating the error. Perhaps the 1 in front of count(*) is a typo?
