That's not a clean startup. The postmaster.pid should not exist.
Are sure you are not running postgresql in > 1 location on this machine...
Do you have an exact copy of a session where you see this happen?
I.e. the pg_ctl start, table updates, pg_ctl stop, pg_ctl start, table
corrupted? Including log files... I feel like we're kind of dancing
around the problem in the dark without enough info.
Please note this is absolutely non-normal behaviour. I've been using
pgsql since v6.5.2 and never had this occur to me.
As for your ulimit settings, what are they, specifically for the
postgres account on this machine, both explicit and inherited?
