Обсуждение: Postgres fails to start
Hi All,
I have experienced that Postgres services was not able to start, I tried from Services and command, and both were failed. Here are the logs I got, please help. (I am using postgres 9.1 and there are plenty disk space left).

2015-04-07 09:01:28 EST HINT: This probably means that some data is corrupted and you will have to use the last backup for recovery.

Hi Michael, Thank you for replying. The file was there, is that ok to remove the corrupted file to recover postgres? "base/2008723533/2107262657.2" Unfortunately, I only have a backup on February. Is there a way I can recover it without losing the recent data?

"base/2008723533/2107262657.2" Be careful here, I would recommend taking a file-level snapshot before going on and do perhaps-stupid things.

Hi Michael, Thank you again. It seems hard to recover, I will go the hard way (lost data). Learned a lesson.
