Hi,
This is my first post to this list, so I hope I am posting it to the correct lists. But I am really stuck and getting pretty desperate at the moment.
This weekend my database crashed while importing some Openstreetmapdata and I can’t get it back to work again. It happened before and normally I would reset the WAL-dir with the pg_resetxlog command. I would loose some data but that would be all.
This time it is somehow different because he doesn’t recognize any of the important files anymore. For example when I try to start Postgresql again with the command:
/usr/lib/postgresql/9.1/bin/pg_ctl -D OSM/ start
I get the following error:
FATAL: could not create lock file "postmaster.pid": No such file or directory
But when I do a ls –l on the directory I can see the file exists.

-rwxr-xr-x 0 postgres postgres 88 Feb 17 08:58 postmaster.pid
I cannot perform any action on the postmaster.pid file. I tried cp, mv and rm, but nothing works. Is there anything I can do to make the system recognize this file again? And get my database up and running? Or is all hopelessly lost?
I have Postgresql 9.1 installed on Ubuntu 12.04.
Kind regards,
Rob.
You don't give a lot of information, but try "sudo rm postmaster.pid" or "sudo -u postgres rm postmaster.pid" if you are sure that postgres is not running.
Cheers,
Cliff
