Andy, Thanks for your help! The var_dump after the pg_execute showed that the execute() method wasn't being called (I left a line out of the calling script). Once I fixed that, I changed pg_execute back to pg_exec and it worked as expected. Now I have to figure out the difference between pg_exec and pg_execute... From what I can tell, pg_exec isn't supported any more and I should be using pg_execute instead... Thanks again.
