PostgreSQL version: 9.0.1
Operating system: Linux
Description: 9.0.1 segmentation fault (sig11) during long-lived
update
Details:
Hi,
I'm using PostgreSQL 9.0.1 on centos 5.4.
I'm running the following update (which takes a few days to run before I get
the error - twice now):
update tab1 set col1 = hashtext(col0) where col1 isnull;
I'm running this update as part of an exercise to purge duplicates, before
creating a UNIQUE index.
Error from PG:
server process (PID 19328) was terminated by signal 11: Segmentation fault
terminating any other active server processes
...
Before I run this again, what's the best way to proceed to get a core dump
so I can run a gdb backtrace to provide more info? Simply 'ulimit -c
5242880' as user postgres and restart PG?
Thanks
