Thread: pgsql: Fix thinkos from 4f4061b for libpq integer parsing

Fix thinkos from 4f4061b for libpq integer parsing

A check was redundant.  While on it, add an assertion to make sure that
the parsing routine is never called with a NULL input.  All the code
paths currently calling the parsing routine are careful with NULL inputs
already, but future callers may forget that.
