The buildfarm got a bit angry after this commit:
https://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=clam&dt=2020-12-30%2003%3A00%3A11

Here is a diff from member clam, that uses ppc64:
select count(*) from test_multirange_gist where mr <@
int4range(10,50);
- count
--------
- 500
-(1 row)
-
+ERROR: unknown multirange operator 4540

This points out to OID_RANGE_MULTIRANGE_CONTAINED_OP.

Please note that you should add a "Discussion:" in those commits to be
able to track down where this stuff has been discussed.
