To save you from having to look at the run-time prune patch, here's
case that break in v18.

create table xy (a int, b text) partition by range (a,b);
create table xy1 partition of xy for values from (0,'a') to (10, 'b');
select * from xy where a = 1 and b in('x','y');
ERROR:  operator 531 is not a member of opfamily 1976
