Re: [BUGS] BUG #2712: could not fsync segment: Permission denied
there is defenitely something terribly wrong in the windows 8.2b1 regarding
file access/locking. 2nd total db lockup today due to file access locks (all
hold by postmaster):

from 17:48:14 on pgsql didn't handle anymore queries until shutdown. as soon
as one restarts postmaster, the file locks are cleared up.
and no, there are no other file locking tools (av scanners and the such)
running - 8.1 on the same box (even on same partition) run fine.

The usual answer to this has been that you're running some
overenthusiastic antivirus software.

Re: [BUGS] BUG #2712: could not fsync segment: Permission denied
in verbose mode, the log shows a little bit more:

The following bug has been logged online:
Bug reference: 2712
Logged by: Thomas H
Email address: [EMAIL PROTECTED]
PostgreSQL version: 8.2b1
Operating system: windows 2003 standard
Description:could not fsync segment: Permission denied
Details:
sometimes we're seeing loads of errors in the log:
2006-10-22 23:48:50 LOG: could not fsync segment 0 of relation
1663/3964774/6409340: Permission denied

{...}
when this happens, there are also files locked within the
data\base\{dbid}\.
access to those files are denied by the os - the files vanish as soon as
postmaster ist stopped restarted.
i haven't yet found a possible reason - i suspect the error to appear
*sometimes* after issuing a VACUUM FULL ANALYZE {tablename} / REINDEX
TABLE {tablename}.
the hardware is checked and ok.
