How c

Answer 1

For anyone running into this issue using DBeaver and getting an error message like this:

ERROR: database "my_stubborn_db" is being accessed by other users
  Detail: There is 1 other session using the database.

Disconnect your current connection, and reconnect to the same server with a connection that doesn't target the database you are renaming.

Changing the active database is not enough.
