Good catch. Here's a patch against CVS HEAD that fixes the problem.

The actual segfault was caused by a double pfree(), but ISTM that
failing to find pg_hba.conf should be a fatal error anyway, so I
increased the priority of the elog() from LOG to FATAL and refactored
the code a little bit.

Bruce: unless anyone has an objection, please apply.

Thanks for the report.

Cheers,

Neil
