Because they're different. The SQL spec says that an empty string
is different from NULL, and so does every database in the world except
Oracle. Oracle, however, does not define the standard.
Hi
I had installed postgresql-8.2.4. After some problems with tsearch2
installation i had the next problem:

Hi all,
I have a column declared as "timestamp without time zone" that I vainly
want to insert a raw timestamp into (i.e. in the format returned by
Perl's or PHP's time()). I know of SQL NOW(), but I want to insert a
"cooked" timestamp from the outside most efficiently. How?
Thanks.

If i have 2 processes running the same 100s of these at the same time i
