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.

process of dropping roles by dropping objects owned by them and privileges
granted to them, or giving the owned objects to someone else, through the
use of the data stored in the new pg_shdepend catalog.
Some refactoring of the GRANT/REVOKE code was needed, as well as ALTER OWNER
code. Further cleanup of code duplication in the GRANT code seems necessary.
Implemented by me after an idea from Tom Lane, who also provided various kind
of implementation advice.
Regression tests pass. Some tests for the new functionality are also added,
as well as rudimentary documentation.
