That doesn't answer the question though, because Tom wanted to know
which of 7.3, 7.3.1, 7.3.4 etc you are running. (You also didn't answer
the same question when I asked you.)

In the spanish list however, he disclosed that this problem happened on
a shared storage system, which is used by two postmasters on different
machines controlled by a heartbeat system. The main server was
accidentaly disconnected from power. I told him that concurrent
postmasters were fatal, but he hasn't confirmed whether they actually
ran concurrently.

Good luck with the upgrade, though I advise you not to use the heartbeat
system until you have really debugged it to work the way you want it to.
(Or not use it at all, and run Slony-I or some such replication system
instead.)
