Weird behaviour of = ANY ( SUBQUERY ) ?
Version - 8.5devel.
Why this doesn't work:
# SELECT 1 = ANY( ( SELECT '{1,2}'::int4[]) );
ERROR: operator does not exist: integer = integer[]
LINE 1: SELECT 1 = ANY( ( SELECT '{1,2}'::int4[]) );
^
HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts.
direct usage of array of course works:
# select 1 = any ( '{1,2}'::int4[] );
?column?

t
(1 row)

Why would you expect it to work? The datatypes aren't compatible.

# select 1 = any ( '{1,2}'::int4[] );
ANY with a sub-SELECT and ANY without one are two completely different
things.
