Here's a version of Jeff's fix1 patch (with a trivial change to the
comment) that applies to HEAD, REL9_0_STABLE, REL8_4_STABLE, and
REL8_3_STABLE; a slightly modified version that applies to
REL8_2_STABLE; and another slightly modified version that applies to
REL8_1_STABLE and REL8_0_STABLE. REL7_4_STABLE doesn't have
tablespaces, so the problem can't manifest there, I think.

I'm currently compiling and testing all of these. When that's done,
should I go ahead and check this in, or wait until after beta4 wraps?
