TAP cone search query fails

Question

Hi! I get an error when trying to use the TAP cone search:

Query (from TAP examples):

SELECT
   TOP 1000
   *
   FROM smash_dr2.source
   WHERE 
      1=CONTAINS(POINT('ICRS', ra, dec),
                 CIRCLE('ICRS', 79.786, -69.656, 0.05 ))

Exception:

java.io.IOException: PSQLException: ERROR: function point(unknown, double precision, double precision) does not exist
  Hint: No function matches the given name and argument types. You might need to add explicit type casts.
