You could get some more info about what's happening by turning on query
logging in the postmaster (start postmaster with -d2, and be sure NOT to
use -S).  But I'll bet that some way or other, PHP is submitting the
same query multiple times.

I have some recollection that pg_pconnect() doesn't behave very well;
you might need to avoid that in favor of a plain connect.  Check the
archives for discussion of pconnect.
