Обсуждение: pg_dumpall + pgdump_oid table + incremental backup

Hi folks,

I'd like to do hourly incremental backups w/ pg_dumpall + git.
But each time I dump out an unchanged data, I get differences
on the temporary pgdump_oid table, which seems to be used to
ensure correct OIDs. This most likely useless change will
unnecessarily fill up my backup.

Is there any way around this ?


thx

Well, you could not use -o, or you could move to a less obsolete
version of Postgres ...
