You tell us.  I don't know of any common extension that would create
a "smallint = text" operator.  (A variant theory is that you didn't
make a new operator, but an implicit cast from smallint to text.
Either way, it almost certainly is a homebrew thing.  Or maybe what
you are running is not stock Postgres?)

It might be interesting to try some direct test, like

SELECT 22::smallint = 'foo'::text;

For me that gives the same "operator does not exist: smallint = text"
error, but I bet your database tries to execute it.
