The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/10/sql-dropsubscription.html Description:
This page has a note about how to set the subscription to not use a slot, but it doesn't mention that the subscription needs to be disabled first. In my case, I had to Google around and then do: ALTER SUBSCRIPTION xxx disable; Then I could set the slot_name. Then I could drop it.
