Обсуждение: pg_restore

Hi,

I was wondering does pg_restore exist prior to 7.1.  I am running 7.0 and
just wondering is there an equivalent I can use with pg_dump to restore a tar
file with the archive.list file.

Thanks

No.

No.  You could try the 7.1 pg_dump/pg_restore with 7.0, but it probably
won't work.  Better plan to upgrade soon, since there are many
enhancements in 7.1.

Actually I believe 7.1.1 and later pg_dump *is* backwards compatible
with a 7.0.* server.  The output script isn't, but it should be possible
to use the newer pg_dump to dump out your 7.0 database in preparation
for upgrading.

Not sure how well tested that mode is, mind you, but it's alleged to
work.  I'd recommend running some experiments before trusting it
completely.  (If you can load a schema-only dump of your 7.0 database
into a 7.1 test installation, and everything looks okay, that's probably
enough testing.)

            regards, tom lane
