pgsql bug found?

["Ronin" <jkoorts@xxxxxxxxx>]

Hi when I do the following function it fills 2 dates per day from 1970
to 2050, except that some months  (typical 2 months per year) have 4
dates for one day. this is totally freaky.. I wonder if postgresql is
tripping over itself making a double entry every now and again.

for instance I constantly get the following entries

"2006-10-01 00:00:00"
"2006-10-01 23:59:59.999"
"2006-10-01 00:00:00"
"2006-10-01 23:59:59.999"

Any ideas?

Here the function

	DECLARE
		yearcnt integer;
		monthcnt integer;
		daycnt integer;

	BEGIN

           FOR yearcnt IN 1970..2050 LOOP
		monthcnt=1;
		FOR monthcnt IN 1..12 LOOP
			daycnt = 1;
			FOR daycnt IN 1..31 LOOP
				insert into datepool values
(to_timestamp(yearcnt||'-'||to_char(monthcnt,'FM00')||'-'||to_char(daycnt,'FM09')||'
00:00:00.000','YYYY MM DD HH24:MI:SS.MS'));

				insert into datepool values
(to_timestamp(yearcnt||'-'||to_char(monthcnt,'FM00')||'-'||to_char(daycnt,'FM09')||'
23:59:59.999','YYYY MM DD HH24:MI:SS.MS'));
	
			
			END LOOP;
		END LOOP;		
           END LOOP;
	
	return;
	
	END;
