What actually Happend:
Running windows 7 on my system and system was shutdown due to power failure. when system restarted, I opened PostgreSQL and all my databases were deleted.
I checked logs and there were some entries
Database system was intrupted ; last known up at (dateTime) Database system was not properly shutdown; automatic recovery in progress Record with zero length at 0/C9B92168 Redo is not required
Can anybody tell me how can i recover my databases, as I don't have restore point.
