Bug reference: 1809
Logged by: Chris Hoover
Email address: chris.hoover (AT) companiongroup (DOT) com
PostgreSQL version: 8.0.3
Operating system: RHEL 4 AS Update 1
Description: invalid pointer on pg_ctl reload
Details:

I was working with my pg_hba.conf file and did a pg_ctl -D <path> reload. I
received the following message, and postgresql shutdown.

[postgres@edipgtst1 eedi]$ pg_ctl -D /database/data/eedi/ reload
postmaster signaled
[postgres@edipgtst1 eedi]$ *** glibc detected *** free(): invalid pointer:
0x082ced00 ***

To make changes to my configuration in 8.0.3, I am having to always to
restarts instead of reloads.

PostgreSQL was installed from the rhel 4 rpms provided on the PostgreSQL
mirrors.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match

What non-comment entries do you have in postgresql.conf?

It's also possible that the problem is being triggered by an unusual
entry in one of the other config files, such as pg_hba.conf. Please see
if you can narrow down what's causing this.

Got it --- we had broken the handling of an explicit specification

in the config file. Thanks for sending along the test case.
