Обсуждение: Restore backup file "with oids"

Hi,

Is there somewhere a script that can do a restore backup file "with oids" in some newer DB where there is no term "with oids"?

There is nothing automatic, some manual work is needed. A couple of ideas:

1. Install an older version of PostgreSQL that still supports WITH OIDS, and restore the dump there. Use ALTER TABLE
SETWITHOUT OIDS, and dump the database again (preferably with v12 of pg_dump). 

2. Create the table manually, but with a regular oid-type column in place of the system column. Do a data-only restore.


You didn't mention what format the backup dump is. If it's in custom format, you can do a data-only restore easily. If
it'sa text sql file, and it's not too large, you can load it in a text exitor and edit manually.

HI,

The first thing I have to say is that I only have a plain backup file "with oids" from "PostgreSQL 8.4.2, 32-bit",

from which I should take the contents of some tables.
Any help from someone who was in a similar situation would help me a lot in resolving this situation.

Thank you Heikki for your solution.
