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); 2022-04-11 17:37:58.426 AEST [28152] WARNING: cache reference leak: cache pg_publication_rel (49), tuple 0/12 has count 1 WARNING: cache reference leak: cache pg_publication_rel (49), tuple 0/12 has count 1 ALTER PUBLICATION ------ Kind Regards, Peter Smith.
