postgres crash when select a record

From
mailtolouis2020-postgres@yahoo.com
Date:
Hello,
 
I wish some could help me on this.
 
I got a table which has 100500 records, when I try to query this particular record
 
select * from cs_sr_mthly_rtn where mthly_rtn_id = 61609;
Postgres crash, and show this errors:
 
server closed the connection unexpectedly
 This probably means the server terminated abnormally
 before or while processing the request.
 
And in the serverlog, it shows:
 
LOG:  server process (PID 395) was terminated by signal 11
LOG:  terminating any other active server processes
FATAL:  the database system is in recovery mode
LOG:  all server processes terminated; reinitializing
LOG:  database system was interrupted at 2008-05-14 12:52:15 BST
LOG:  checkpoint record is at 0/48DEC034
LOG:  redo record is at 0/48DEC034; undo record is at 0/0; shutdown TRUE
LOG:  next transaction ID: 0/705241; next OID: 49152
LOG:  next MultiXactId: 1; next MultiXactOffset: 0
LOG:  database system was not properly shut down; automatic recovery in progress
LOG:  redo starts at 0/48DEC07C
LOG:  unexpected pageaddr 0/433AC000 in log file 0, segment 74, offset 3850240
LOG:  redo done at 0/4A3ABFC0
LOG:  database system is ready
 
Because of this, I'm not able to do pg_dump backup anymore.
 
Anyone can help me to solve this problem?
 
 
Thanks
louis

Looks loke you tried to run your query whilst postgres was recovering from an improper shutdown, try once again when the last thing in the log is

No, I didn't run the query when the DB is in recovering.

I did that after database system is ready

I can't to eliminate PostgreSQL bug, but sometimes this problem
signalize hw problems. You can search in archive similar cases.
Postgres crashes, because stored row are in broken format. There are
some projects that would solve it better -

Definitely run some tests on the hardware, like memtest86, and some
drive tests for bad blocks.
