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.

TIP 5: don't forget to increase your free space map settings
