Hi everybody,
I'm facing a strange problem with a relatively simple sub select
whereas everything else runs perfect on this machine (PG 8.4.2 @
Fedora 12, Core2 E4600, 4GB, 2 x 320GB).
# SELECT DISTINCT name FROM bbr_parts WHERE id IN (SELECT part_id FROM
bbr_v_office_to_parts WHERE office_id=39 AND office_type=9);
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 sub select has no problems and returns 2 rows correctly:
# SELECT part_id FROM bbr_v_office_to_parts WHERE office_id=39 AND
office_type=9;
part_id
---------
412
394
Replacing the sub select with these hard-coded numbers works as well:
SELECT DISTINCT name FROM bbr_parts WHERE id IN (412, 394); -- okay
What I tried so far to circle the problem:
* REINDEXing all related tables didn't solve the problem (a tip from
Tom Lange to a similar problem I've found in another posting).
* Dropped RI Constraint.
* Decreased shared_buffer down to 1MB (the minimum postmaster starts).
* Dropped the complete database and re-created it. Then, the SELECT
worked about 10 times until the problem comes back!
When nothing else helps, I will downgrade from PostgreSQL 8.4.2 to
8.3.7. Thank you for your comments.
