When pg_recvlogical was introduced in 9.4, the --dbname option was not required for --drop-slot. Without it, pg_recvlogical --drop-slot connected using a replication connection (not tied to a specific database) and was able to drop both physical and logical replication slots, similar to pg_receivewal --drop-slot. However, commit 0c013e08cfb unintentionally changed this behavior in 9.5, making pg_recvlogical always check whether it's connected to a specific database and fail if it's not. This change was expected for --create-slot and --start, which handle logical replication slots and require a database connection, but it was unnecessary for --drop-slot, which should work with any replication connection. As a result, --dbname became a required option for --drop-slot. This commit removes that restriction, restoring the original behavior and allowing pg_recvlogical --drop-slot to work without specifying --dbname. Although this issue originated from an unintended change, it has existed for a long time without complaints or bug reports, and the documentation never explicitly stated that --drop-slot should work without --dbname. Therefore, the change is not treated as a bug fix and is applied only to master.
