Check integrity between servers
Would be possible to check the integrity between two database servers?
Both servers are slaves (streaming replication + wal_files) but I believe
one of them, when recovered from wal_files in a fast outage we got, got
recovered not 100%.
How could I check the data between both DB?
I'm using Postgres 9.2
Cheers

As far as I could see, checksum is only allowed on Postgres 9.3?

So can't use that! Any other ideas?

Did you mean to say recovery is not successful or complete ? How did you
know that recovery is not 100% ? Any errors, messages etc ?

That is something which Application needs to do. From database perspective
you can check if the databases are in complete sync.
