The following bug has been logged online:

Bug reference: 1473
Logged by: Brian B.

PostgreSQL version: 8.0.1
Operating system: FreeBSD 4.11-STABLE
Description: Backend bus error, possibly due to ANALYZE
Details:

Hello,

I am loading some spam/ham data/tokens, to be used for the dspam anti-spam
software, into PostgreSQL. After a few hours of inserting and updating the
existing data, the backend crashes with a signal 10 (bus error). I am also
running an ANALYZE command to help keep the indexes up to date every 10
minutes. I have rebuilt PostgreSQL with debugging enabled and have a
resulting core dump. I am not sure who to send this to, however. The
backtrace using the core file is as follows:

#0 0x80c4b52 in transformExpr (pstate=0x86fa630, expr=0x85ec148)

I have compiled PostgreSQL with pthread for pl/python capability.

Thanks,
