DROP CONSTRAINT
This form drops constraints on a table. Currently, constraints on tables
are not required to have unique names, so there may be more than one
constraint matching the specified name. All matching constraints will be
dropped.
To my knowledge, it is no longer possible to create constraints with the
same name for the same relation. When you create a constraint and specify
the same name explictly, an error is raised. Implicit constraint creation
won't choose an existing name either and up to now you could not rename a
constraint. Renaming works with the patch I sent in a few hours ago but this
patch as well won't allow constraints with identical names on the same
relation.
The attached patch thus removes the note in the docs.

the latest release notes there is a latin1 character that shouldn't be
there so I made a patch to fix that. This patch also fixes some old
entries that uses o instead of ö (which is also wrong but not as
bad as including a latin1 character in the sgml file).

Map them to a single day, so '30 hours' is 'AM'.
Have to_char(interval) and to_char(time) use "HH", "HH12" as 12-hour
intervals, rather than bypass and print the full interval hours. This
is neeeded because to_char(time) is mapped to interval in this function.
Intervals should use "HH24", and document suggestion.
Allow "D" format specifiers for interval/time.
to fail to successfully build the release candidates.
However, a patch has emerged (thanks, Seneca!) that does allow it to
work, and which I'd expect to be portable (better still!).
We are still actively pursuing why it breaks, but supposing that still
remains outstanding, at least the following would allow AIX users to
better survive a build...

necessary, and be careful to refer to the right version where it is
useful to do so. This partially reverts an ill-considered search and
replace from a few months ago.
