postgreSQL - in vs any

Question

I have tried both

1) smthng = any(select id from exmplTable)

2) smthng in (select id from exmplTable)

Answer 1

This may be an edge case but:

select * from myTable where id IN ()

will produce: ERROR: syntax error at or near ")"

but

select * from myTable where id = ANY('{}');

Will return an empty result set
