I'm seeing the following failure in the rules regress test:

$ diff expected/rules.out results
1338c1338
< shoelace_data | log_shoelace | CREATE RULE log_shoelace AS ON UPDATE TO shoelace_data WHERE (new.sl_avail <> old.sl_avail) DO INSERT INTO shoelace_log (sl_name, sl_avail, log_who, log_when) VALUES (new.sl_name, new.sl_avail, 'Al Bundy'::name, 'Thu Jan 01 00:00:00 1970'::"timestamp");

$

The actual result corresponds to the former output, and is indeed what
I would expect, given that text_timestamp() is (and should be)
non-cachable. Are you sure this expected file is correct?

I'm also seeing rather massive failures in horology, but this evidently
is because horology-no-DST-before-1970.out hasn't been updated ...
