[GENERAL] keeping WAL after dropping replication slots

[Tom DalPozzo]

Hi,
I had two replication slots on my primary. Slaves off and (around 800) WALs
kept as expected.
I dropped those slots but over time, the system kept on adding new WALs
without reusing them or deleting them.
Only after shutdown and restart the system deleted those WAL files.
Is that ok?
