Обсуждение: problem running postmaster

Hello,

I am having problems running postmaster.
I get the following error:

DEBUG:  invoking IpcMemoryCreate(size=1466368)
PANIC:  invalid checksum in control file


The postmaster then exits.

What control file is it talking about?
Is this a common error?

Thanks for any help

$PGDATA/pg_clog

Control files reside in there

No this is not common. Was there a hard system crash and psotgresql data reside
on a non-journalling file system?

If yes, you are looking at an inconsistent database.

Please confirm.

No; I don't think I've ever seen it reported from the field before.
How did you get into this state?
