Hello,
This is a feature I have wanted for a long time, thank you for your work on
this.
The latest patch [1] applied cleanly for me. In dbcommands.c the comment
references a 5 second delay, I don't see where that happens, am I missing
something?
I tested both the dropdb program and the in database commands. Without
FORCE I get
the expected error message about active connections.
postgres=# DROP DATABASE testdb;
ERROR: source database "testdb" is being accessed by other users
DETAIL: There is 1 other session using the database.
With FORCE the database drops cleanly.
postgres=# DROP DATABASE testdb FORCE;
DROP DATABASE
The active connections get terminated as expected. Thanks,
[1]
