Обсуждение: <> syntax legal?

Is it legal syntax to use <> instead of != in a Postgres query?

I didn't see it listed on:

http://www.postgresql.org/docs/7.4/static/sql-syntax.html

but wanted to ask to make sure.

peter=# SELECT (1 <> 2) != (3 <> 4);
 ?column?
----------
 f
(1 Zeile)

All signs point to "yes".

It's not just legal, <> is the official SQL compliant non-equality operator.
