Slightly off-topic and a shameless (?) plug, but once you have managed to create your stored procedure, please have a look at DBIx::ProcedureCall, which creates Perl wrappers for stored procedures, eliminating the need for writing SQL by hand.

I just added PostgreSQL support yesterday, and am looking for testers. With it you could call your function like so 

use DBIx::ProcedureCall qw( poo );
my $result = poo ($dbh, 12345);

As for your problem, I can only offer a work-around: Create the function with the psql command line tool (not with Perl/DBI). You only have to do this once (when installing your program), right?
