The reason for that is there is little reason for users of the database
to ever run those. Most (possibly all) of the the packaged builds will
run the regression tests as part of the build process. So the odds of
you finding an error with them is pretty low.
I'm getting the impression you think that the regression tests are
somehow useful for performance testing. They aren't; they are strictly
code quality tests. The only performance testing tool that comes with
the database is pgbench, which is a tricky tool to get useful test
results from.
