Here is another example:
2003-06-05 21:27:08 WARNING: Rel psessions: Uninitialized page 185 - fixing
psessions is often read from and written to, but it is not very big
(thousands, perhaps tenthousands of rows) and it is regularly vacuumed
(every 5 to 15 minutes). These messages appear under heavy load only (more
than 700 concurrent connections to the backend).
Since then (2003-06-05) we didn't get this message again.
I cannot see any pattern there, but at least with our old server, those
messages came just ahead some hardware problems (pg_clog problems, tables
were gone). But our new server right now is running very smoothly.
I will upgrade to 7.3.3 as soon as I find some time.
