I would think that any performance testing would belong in the regression
suite.  And as anyone who lived through the TPC-A/B/C wars knows, it is
possible to write or tune to the test suite, which may or may not reflect
reality.  (Reality is SO variable!)

I always thought the best place to test is with a copy of your real
data...  I'd certainly be willing to flip a ./configure switch or GUC to
test it myself.  I'm sure others would too.  But it's probably easy enough
to just hack the configure script myself.  Or is this one of those things
that fraught with dependency issues?

Just edit src/Makefile.global after running configure, and add "qsort.o"
to the "LIBOBJS =" line.  Then build as usual.
