Thread: Restore single table from pg_dumpall.
Greetings,
I have been asked by a programmer to restore a single table from a PG_DUMPALL backup.
Is this possible, and if so, would anyone be able to tell me please, what PSQL options and switches are required? Running PostgreSQL 8.1.3.
Thanks in advance,
Jim.

Running PostgreSQL 8.1.3. Not sure whether this is an option for you, but I'd make a copy, fire up vim and strip all I don't want out of the copy. If I wanted to be able to restore individual databases I'd dump them individually. Cheers, Andrej

Running PostgreSQL 8.1.3. This is a lot simpler with a tar or custom format backup from pg_dump. Using that, you could dump the ToC and modify it to select the table you want to restore. With a pg_dumpall backup you might just be better off restoring the whole thing into an empty cluster, and then dump the one table only from there. Unless it's small enough to load into a text editor, of course. -- "A government that robs Peter to pay Paul can always depend upon the support of Paul." - George Bernard Shaw

Almost guaranteed to be a whole lot faster than loading a large file into vi. -- Jim Nasby jim@nasby.net EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)
