Subject: [PATCH v1] doc: Remove the libpq environment note from
 pg_combinebackup

pg_combinebackup does not connect to a server: it reads local backup
directories.  It does not link or use libpq (its only dependency is
frontend_code / libpgfeutils), so the libpq environment variables do not
apply to it.  The note was copied from pg_basebackup, which does use
libpq.  Remove it; the PG_COLOR note below is unaffected.
