Two things:

1.) Do backups
2.) Disable write caching in your I/O sub system unless it's battery backed.

Shutdown PG, backup $PGDATA directory, start PG, try REINDEX DATABASE
<you_db>;. If that doesn't help anything, there are some tools available
on pg foundry to inspect the raw files in $PGDATA. You might be able to
get some of your data back using them.
