Re: row filtering for logical replication

FYI, I was playing with row filters and partitions recently, and while
doing something a bit unusual I received a cache leak warning.

Below are the steps to reproduce it:


test_pub=# CREATE TABLE parent(a int primary key) PARTITION BY RANGE(a);
CREATE TABLE

test_pub=# CREATE TABLE child PARTITION OF parent DEFAULT;
CREATE TABLE

test_pub=# CREATE PUBLICATION p4 FOR TABLE parent WHERE (a < 5), child
WHERE (a >= 5) WITH (publish_via_partition_root=true);
CREATE PUBLICATION

test_pub=# ALTER PUBLICATION p4 SET TABLE parent, child WHERE (a >= 5);
ALTER PUBLICATION

test_pub=# ALTER PUBLICATION p4 SET (publish_via_partition_root = false);

WARNING:  cache reference leak: cache pg_publication_rel (49), tuple
