A lot of those test cases involve setting non-default configuration
parameters and/or stopping/starting the postmaster. So I can't see how
we would run them against a pre-existing live cluster, which is the usual
meaning of "make installcheck".
I think what you're imagining is skipping redundant builds of the
"tmp_install" tree by using an installation tree with a temporary $PGDATA
directory. That seems like a fine idea, but we need another word for it.
