I'm using PHP compiled with Postgres client library version 7.4.1.  No real
oddball setup, everything is unmodified from PHP and Postgres distributions.
Some queries have relatively large sets of data returned from server ->
client (possibly as much as 1MB), but nothing approaching the ~962 Mb number
above.

Queries are all SELECT, INSERT, UPDATE.  I wish I could go into more detail,
but I'm very unfamiliar with the Postgres Client<->Server Protocol.

Thanks,

Jason
