Well, the query is already written, so I would use that, FWIW.

test.sh did that, until I noticed that we need to worry about
pg_regress from the past branches to be compatible in the script
itself because we need to run it in the old source tree. This makes
the whole much more complicated to maintain, especially with the
recent removal of input/ and output/ folders in the regression tests
