Hm, looks like I broke this in 8abb3cda0. Should have learned by now
that long-lived caching of ExprState trees is dangerous. The proximate

I was getting segfaults while working on the current master for a while.
This is the shortest way I could found to reproduce the problem:
create or replace function is_distinct_from(anyelement, anyelement)
returns boolean language sql
as 'select $1 is distinct from $2';
create operator !== (
proc
