And now you know why you're supposed to have a backup :-(
The bad news is it sounds like your database may be corrupted. The good
news is it might be possible to recover most of it.
1. Stop the database
2. Take a complete file-level backup of *all* the files in your
PostgreSQL data directory - data, postgresql.conf, xlog stuff etc.
3. Try to start the database and see what you get in the logs. Post the
log errors here.
