Thread: IS DISTINCT FROM vs. ANY

Folks,

Shouldn't this work and produce a "true?"

SELECT NULL IS NOT DISTINCT FROM ANY(ARRAY['a',NULL]);
ERROR:  syntax error at or near "ANY"
LINE 1: SELECT NULL IS NOT DISTINCT FROM ANY(ARRAY['a',NULL]);

Cheers,
David.

It should, but probably depends on whether "IS NOT DISTINCT" should be
considered an "operator".

Got caught by the same thing a couple of days ago.
