Rails + Postgres drop error: database is being accessed by other users

Question

I have a rails application running over Postgres.

I have two servers: one for testing and the other for production.

Very often I need to clone the production

Answer 1

Here's a quick way to kill all the connections to your postgres database.

sudo kill -9 `ps -u postgres -o pid` 

Warning: this will kill any running processes that the postgres user has open, so make sure you want to do this first.
