Select gives the wrong results - Mailing list pgsql-general

Dear all:

I am fairly knowledgeable about PostgreSQL but this behaviour is
stumping me. Any help would be wonderful. If you think it is a bug, let
me now and I'll file one.

(select values in DB (date stamps) between Jan 1, 2000 and Jan 1, 2005,
no results)

db_name=# SELECT * from person_detail WHERE field='2' AND
value>'946702800' AND value<'1104555600';
 id | person | field | value
----+--------+-------+-------
(0 rows)

(select values in DB (date stamps) between Jan 1, 2003 and Jan 1, 2005, 4
results (!))

db_name=# SELECT * from person_detail WHERE field='2' AND
value>'1041397200' AND value<'1104555600';
  id  | person | field |   value
------+--------+-------+------------
 1187 |    454 |     2 | 1051156800
 1188 |    460 |     2 | 1053316800
 1219 |    472 |     2 | 1057723200
 1181 |    441 |     2 | 1042520400
(4 rows)

The first select should have those 4 results plus any more. We tried
putting quotes (") around the word 'value' to see if that made a
difference, and no it didn't. We tried reversing the two clauses and
that made no difference.

Here's another funny one. Not the one that doesn't belong.

db_name=# SELECT * from person_detail WHERE field='2' AND
value>='1000000001' AND value<='1104555600';
  id  | person | field |   value
------+--------+-------+------------
    3 |    218 |     2 | 1017464400
  253 |    295 |     2 | 1002340800
  514 |    323 |     2 | 100155600
 1126 |    405 |     2 | 1006750800
 1179 |    439 |     2 | 1035172800
 1187 |    454 |     2 | 1051156800
 1188 |    460 |     2 | 1053316800
 1219 |    472 |     2 | 1057723200
 1181 |    441 |     2 | 1042520400
 1152 |    434 |     2 | 1032321600
 1129 |    410 |     2 | 1024027200
(11 rows)

Anyone see what's going on here?

Thanks!
Crystle
