From f375d5d6f95fbcc3a98e9853cf597fbdd06d65e0 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>

Subject: [PATCH] Cause pg_regress to invoke the temporary postmaster as
 'postgres' not 'postmaster', so as not to depend on the existence of the
 postmaster symlink.  Also, implement postmaster-still-alive and
 postmaster-kill operations for Windows, per Magnus.
