The following bug has been logged online:
Bug reference: 1116
Logged by: Vic Ricker
Email address: vicricker@charter.net
PostgreSQL version: 7.4
Operating system: Linux (Redhat 9)
Description: "insert into" from "select" crashes backends
Details:
I apologize in advance for being an idiot. :-)
That said, we're having a problem with the backend crashing when we execute
this query using psql:
\set VERBOSITY verbose
insert into option_history
(option_symbol, stock_symbol, expiration_year,
end_of_day, last_sale, volume,
strike, bid, ask, open_interest)
select option_symbol, stock_symbol, expiration_year,
end_of_day, last_sale, volume,
strike, bid, ask, open_interest
from option_history_temp;
The only output is:
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
The logs indicate that it crashed with a signal 11:

I would like to debug but I can't get it to generate a core file. I removed
the ulimit from redhat's startup script but that didn't seem to help.
We're running PostgreSQL 7.4.2 from the RPMs for Redhat 9 from
postgresql.org. We started experiencing the problem after replacing a
failed server and upgrading to Redhat 9 from 8 using whatever version of
postgreSQL comes with RH8.
The architecture is Intel (actually AMD), 512M RAM, the database is on a 56G
RAID1. Kernel version is: 2.4.20-20.9
Here's a dump of the schema for the tables:

I've dumped the two tables out, unfortunately, the big one is over 200 megs
compressed. I'm going to load them into a test server so I can reproduce
the problem without affecting our production environment.
The FAQ suggests to use the debugger to connect to the postgres process.
This should help with my problem of not being able to get a core file. I've
installed the debug RPM. Is there a special procedure for using the debug
libs and stuff?
any suggestions on how to proceed?
