[Zope] ZPygreSQL woes

[ndf@rocketmail.com]

I've run into a problem with Zope with PostgreSQL.  The query runs and
runs and runs till all the memory on the server is used up and Zope
falls over.  Everything works fine on a small table but comes apart as
the number of fields in a table increases.  For example, the table that
I'm trying to query has 18 fields.  I'm running postgresql-6.4.2, the
ZPygreSQLDA is straight off of the Zope site.  I've tried Zope versions
from 1.10 all the way up through 2.0.0b1.  Has anyone else had this
problem?  This is a very serious issue for me.  Any help would be
greatly appreciated if I'm doing something wrong.
