The second way is the way it should have been done all along.

Probably the best fix is to add a command-line switch to pg_regress
to instruct it to use -i, and then have the makefile test
HAVE_UNIX_SOCKETS to decide whether to pass that switch.  This way,
hand invocation of the script could easily run the test both ways,
on machines where that's possible.
