We have had and used this basic dumb useful aggregate in PG 13 and earlier:
CREATE OR REPLACE FUNCTION _final_mode(anyarray) RETURNS anyelement AS $BODY$ SELECT a FROM unnest($1) a GROUP BY 1 ORDER BY COUNT(1) DESC, 1 LIMIT 1; $BODY$ LANGUAGE sql IMMUTABLE;
I can't seem to figure out how to adjust the mode(anyelement) bit now for PG 14 and the loss of anyarray. Changing STYPE to anyelement yields "function array_append(anyelement, anyelement) does not exist" and changing it to anycompatiblearray yields:
ERROR: cannot determine transition data type DETAIL: A result of type anycompatiblearray requires at least one input of type anycompatible, anycompatiblearray, anycompatiblenonarray, anycompatiblerange, or anycompatiblemultirange.
What's the obvious thing I am missing here? Thank you.
