We have a very old backup so I'll try desperate to repair.
If I can't repair I want to skip the error and start server with only
healthy data, no matter if I lose some table page, entire table or
even entire database because the server has many databases inside.
Currently the database is not starting, when I try to start I got the

The first advice here is:
* backup your data files before any attempt to fix the issue.
It might be a hardware failure that corrupted your data (specifically
your transaction logs).
It might be a bug on that specific version, what is your minor release
number?
* As a last resort you could use pg_resetlog, it's a binary that
resets the information in the control file and transaction logs.
http://www.postgresql.org/docs/8.3/static/app-pgresetxlog.html
but please backup your data directory first.
After that, if the server starts up successfully, perform a pg_dump /
pg_dumpall A.S.A.P and reload your data on a new data cluster.
