Recovery Data Cant Be!!! - Mailing list pgsql-general

Hi!!
There is an app to recover data for postgres after inapropiate server
shutdown or power electrical down?
I have a great problem. My system go down inapropiate and now my server
doesnt up.
What 's up with my data?
I lost my data?
I dont believe that a robust database like postgres is so weak for power
down and understand that can go down electrical power but fail 2 ups.

If somebody has any idea to help me this is the log file

The server must be started under an unprivileged user id to prevent
a possible system security compromise.  See the documentation for
more information on how to properly start the server.

        This probably means that some data blocks are corrupted
        and you will have to use the last backup for recovery.
