Обсуждение: Upgrading 7.3 -> 7.4.5
Hi, situation: old server backup. Backup of Postgresql data files. Postgres 7.3.x was running. New server has version 7.4.5 - how do I get the old data in my new database? Copying didn't work - complains about different versions. TIA!
Hi,
You try to dump with -d (dump data as INSERT, rather than COPY,
commands) option of pg_dump and import this in 7.4?

Read this part of the manual? http://www.postgresql.org/docs/8.0/static/install-upgrading.html

You can't take file system level backups under a running postmaster and expect to use those to recover a database. You either need to shut the postmaster down or use pg_dump(all) to make a live dump. > New server has version 7.4.5 - how do I get the old data in my new database? > Copying didn't work - complains about different versions. When switching between major versions (such as 7.3.x to 7.4.x) you need to do a dump and restore. If possible you should use the pg_dump client of the newer version to do the dump, as newer versions do a better job of handling dependencies in dumps.
Well ... I don't have an old version running to make a dump - that would be easy. I just got the files in a backup-directory ... Any ideas? Thanks!

You can try reinstalling the old version and doing the dump. However if the postmaster was running when you made the backups you might be in trouble.
