What do you mean "neither worked"?
the second form works just like a charm. I checked it with PG 7.3.3, DBI
1.14 and DBD::Pg 0.95.

What error and where is that coming from? If I use the comment hack it
doesn't show any message in the postmaster log. It is totally happy with
it and shows exactly the symptom you described.

I'm not too familiar with Perl, but if DBD blindly forwards the query
given in the string argument of prepare() into libpq's pg_exec() ... and
it is supposed to do it that way ... then it is possible to pass
multiple statements. This is a long standing functionality of the
frontend/backend protocol.
