Sheesh guys, "the horology tests fail at DST boundaries" is not only
ancient project folklore, but is well documented:
http://www.postgresql.org/docs/7.3/static/regress-evaluation.html#AEN23380
saith

: Some of the queries in the horology test will fail if you run the test
: on the day of a daylight-saving time changeover, or the day before or
: after one. These queries assume that the intervals between midnight
: yesterday, midnight today and midnight tomorrow are exactly
: twenty-four hours -- which is wrong if daylight-saving time went into
: or out of effect meanwhile.

I could understand some newbie making these complaints, but y'all have
little excuse...
