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).

diff --git a/DB-net79.sql b/DB-net79.sql
index 89b682d..c8be6d6 100644
           
--- a/DB-net79.sql
           
+++ b/DB-net79.sql
           
@@ -12,7 +12,7 @@ SET client_min_messages = warning;
           

CREATE TEMPORARY TABLE pgdump_oid (dummy integer) WITH OIDS;
COPY pgdump_oid WITH OIDS FROM stdin;
-22336387       0
           
+22336547       0
           
\.
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 ?
