The following bug has been logged online:
Bug reference: 3731
Logged by: Daniel Cristian Cruz
Email address: cruz@senai-sc.ind.br
PostgreSQL version: 8.2.4
Operating system: Red Hat ES 4
Description: ash table "PROCLOCK hash" corrupted
Details:
A few moments ago I got the following message, but didn't found any
reference on the internet (including lists).
Nov 8 13:50:56 SERVER postgres[18874]: [5-1] user=XXX,db=XXXPANIC: hash
table "PROCLOCK hash" corrupted
The error showed after some query that where logged because were slow (more
than 5 seconds), in which they had a very big list of values in a NOT IN
clause (not sure if this caused the problem).
I don't know if this is a bug or not.

Well, it shouldn't have happened, so either it's a bug or you had a
hardware glitch. But unless you can find a way to reproduce it I'm
not sure we can do much about it. I doubt your large NOT IN was
relevant --- more likely it'd be something associated with inter-process
interactions.
