The problem is not with passing the connection hanlde to pg_exec exactly.
If you create the connection hanlde in one function, then pass that handle
to another function that actually does the call to pg_exec, then sometimes
there are problems. In my own case, I figured out if after creating the
connection hanlde, I call two functions that each call pg_exec, then this
normally works, but when a function makes two calls to pg_exec, then the
NEXT function has a problem.

$dbc = pg_connect(); func1($dbc); func2($dbc);
This works fine if func1() and func2() each contain a single call to pg_exec.
If func1() contains two calls to pg_exec(), then func2 fails on call to
pg_exec.

I should also point out, that this was never a problem before I did
upgrades in October. Unfortunately, I upgraded OpenBSD, pgsql, php(3->4)
and phplib all during the same week.
