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(at)edipgtst1 eedi]$ pg_ctl -D /database/data/eedi/ reload
postmaster signaled
[postgres(at)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.
