That's the issue I was talking to Tom about above. Need to
unconditionally have

+# We need to make pg_regress use psql from the desired installation
+# (likely a temporary one), because otherwise the installcheck run
+# below would try to use psql from the proper installation directory,
+# which might be outdated or missing. But don't override anything else
+# that's already in EXTRA_REGRESS_OPTS.
+EXTRA_REGRESS_OPTS="$EXTRA_REGRESS_OPTS --bindir='$oldbindir'"
+export EXTRA_REGRESS_OPTS

in all branches (i.e. ressurect in master, do it not just in the
--install case in the back branches, and reference $oldbindir rather
than $bindir in all branches).

Think we don't need LD_LIBRARY_PATH, due to the $(with_temp_install)
logic in the makefile. In the back branches the --install branch
contains adjustments to LD_LIBRARY_PATH (but still references $bindir
rather than $oldbindr).
