&gt; I am running Python 1.5.

Therein lies the problem... :)

Since it appears you have the requirement of supporting old python
versions, attached is just the pgdb.py part of the patch (with a fix for
DateTime handling). It has the same functionality but certainly won't be
quite as fast. Given the absence of _PyString_Join in python1.5, it's a
pain to get the C variants working for all versions. The pgdb.py patch
does leaves the hooks in, should someone wish to do the optimization at a
later point.
