Thanks Michael and Steve.

Related question: If I previously had a

IF EXISTS (select ...)

statement, and the 'select ...' part now needs to be run with EXECUTE,
how do I check for existence?  It looks like I need to do an 'INTO'
with a row variable?  I can't seem to find an example snippet of how
to accomplish this in the pg docs.  Where should I be looking?

Thanks again!
Gary
