Per report from Han Holl.  Also some trivial code cleanup in write_syslog.

	regression=# select '23:59:59.9'::time(0);
	   time
	----------
	 24:00:00

	This is bad because:

	regression=# select '24:00:00'::time(0);
	ERROR:  date/time field value out of range: "24:00:00"

The last example now works.

of client_min_messages (fatal + panic) are valid and also fixes a slight
issue with how psql tried to display error messages that aren't sent to
the client.

We often tell people to ignore errors in response to requests for things
like "drop if exists", but there's no good way to completely hide this
without upping client_min_messages past ERROR.  When running a file like

SET client_min_messages TO 'FATAL';

DROP TABLE doesntexist;

with "psql -f filename" you get an error prefix of
"psql:/home/username/filename:3" even though there is no error message to
prefix because it isn't sent to the client.

I'm not clear on what the double-backslash idea was intended to fix,
but it breaks at least mingw GNU Make.  Per report from Thomas Hallgren.

make_restrictinfo_from_bitmapqual.  The likelihood of finding duplicates
seems much less than in the AND-subclause case, and the cost much higher,
because OR lists with hundreds or even thousands of subclauses are not
uncommon.  Per discussion with Ilia Kantor and andrew@supernews.
