Is there any tools for replication in postgres which can doing the following :

  1. automatic DDL replication?
  2. when master DB down, then slave will become the master DB immediately.
  3. my company database is +- 5GB size

i have search some tools for replication which is slony and bucardo (and all trigger based replication system cannot doing the DDL replication)(source). and for 9.0 Streaming Replication (built in on postgres),Gabriel Weinberg (DuckDuckGo)said “Steve Signer wrote up some cases where you wouldn’t want to/be able to use the built-in replication”

so 3 tools i found (slony,bucardo and 9.0 SR) , doesnt meet my criteria to do the postgres. is there any suggestion?

    1. automatic DDL replication?

    => Use streaming replication, replicates everything.

    1. when master DB down, then slave will become the master DB immediately.

    => pgPool does it’s job over here, works fine.

    1. my company database is +- 5GB size

    => That’s very small, don’t worry.
