array_cat in PG-14 changed signature breaks my custom aggregate

[Andreas Joseph Krogh]

Hi, I have this, for historical reasons: 

CREATE AGGREGATE array_aggarray(anyarray) (
 SFUNC = array_cat, STYPE = anyarray); 



...which now breaks in pg-14b1: 

ERROR: function array_cat(anyarray, anyarray) does not exist 


I see the argument data-types have changed from anyarray to 
anycompatiblearray, but that doesn't really tell me anything. 

Do I have to change the signature of my aggregate to take anycompatiblearray 
as argument?
