Hmm, create table w (a point);
# select * from w order by a fetch first 2 rows with ties;
ERROR: could not identify an ordering operator for type point
LINE 1: select * from w order by a fetch first 2 rows with ties;
^
HINT: Use an explicit ordering operator or modify the query.
I'm not sure that the HINT is useful here.
