Hi folks,

I'm doing regular (hourly) dumps and putting them into git
(and automatically pushing it to several git servers).

The problem is: the dumps are always differing (even if nothing
happened in that db).

DROP TABLE pgdump_oid;


This unnecessarily pollutes the history and procudes high load
when git-gc / git-repack runs.

Is there any way to get rid of these differences ?

(1) don't specify --oids
or
(2) update to something newer than 8.0 ... we haven't emitted that
for a long time.
