The main point I'm on about here is that "make check" must not require
root privileges.  That is absolutely not negotiable (even if it were
sane from a security standpoint, which is ridiculous anyway).  I don't
think "make installcheck" should require root either, although there
might possibly be a little more wiggle room there.  If it's infeasible
to test sepgsql usefully without root involvement, then it can't be
tested within the existing regression test framework.  So maybe just
pushing the issue out to a separate shell script that you can choose
to invoke by hand is a reasonable compromise.

I think it should be possible to still use all the existing testing
infrastructure if the check/test script does something like
        make REGRESS="label dml misc" check

BTW, I think this line of argument also casts serious doubt on whether
REGRESS_PREP is a useful concept at all.  I'm more than half tempted to
revert the patches that added that to the regression test
infrastructure.  Do we still need the --launcher option, either?
