Is there a way out if someone accidentally executes the same test case against PG12?
testdb=# create table partitioned (a int, b int) testdb-# partition by list ((row(a, b)::partitioned)); CREATE TABLE testdb=# DROP TABLE partitioned; ERROR: cache lookup failed for type 18269
Ah, I wasn't sure that additional tests on a table would be worthwhile enough. Thanks for tweaking and pushing!
