Did it help? If yes - maybe you can help me?

As of yesterday OmniPITR got following changes/fixes:

  1. Fixed bug which caused immediate finish request be treated the same as smart finish request.
  2. Fixed problem with using omnipitr-backup-slave on PostgreSQL 9.0 slave, which is using streaming replication.
  3. Added option to omnipitr-restore, so that you can now use it for streaming-replication slaves

I'm very ashamed of the first thing (smart/immediate finish request), as it was simply my lack of test.

Second thing – the problem was that with streaming replication slave behaves a bit differently than normally, and so the backup procedure had to be modified.

As for third – restore command in streaming replication environment has to behave differently than normal restore command – i.e. it should finish, with error, as soon as it will be called for wal file that does not exist in wal archive. Which is direct opposite of what should be done normally.

Now, omnipitr-restore got switch (-sr) to make it work correctly in SR situation.

Links for svn/docs are listed on project page.
