- new function justify_interval(interval)
- modified function justify_hours(interval)
- modified function justify_days(interval)
These functions are defined to meet the requirements as discussed in
this thread. Specifically:
- justify_hours makes certain the sign bit on the hours
matches the sign bit on the days. It only checks the
sign bit on the days, and not the months, when
determining if the hours should be positive or negative.
After the call, -24 < hours < 24.
- justify_days makes certain the sign bit on the days
matches the sign bit on the months. It's behavior does
not depend on the hours, nor does it modify the hours.
After the call, -30 < days < 30.
- justify_interval makes sure the sign bits on all three
fields months, days, and hours are all the same. After
the call, -24 < hours < 24 AND -30 < days < 30.

returning "ASCII code of the first character of the argument"

Table 9-6. "Other String Functions").
Presumably this should read "ASCII code of the first byte of the
argument",
which is what is returned when the argument is a multi-byte character
(although then with UTF-8 at least that might not necessarily be an
ASCII
code).

multiples of the page size (at least, that's how I interpret the
Darwin code).

more compliant with the error message style guide. In particular,
errdetail should begin with a capital letter and end with a period,
whereas errmsg should not. I also fixed a few related issues in
passing, such as fixing the repeated misspelling of "lexeme" in
contrib/tsearch2 (per Tom's suggestion).
creation of a shell type. This allows a less hacky way of dealing with
the mutual dependency between a datatype and its I/O functions: make a
shell type, then make the functions, then define the datatype fully.
We should fix pg_dump to handle things this way, but this commit just deals
with the backend.
