I am running a postgres database on the google cloud services. I have run several (too heavy) update queries this morning. As they took too long I have shut them down and restarted my device to reset all connections that weren’t closed properly.

The problem is that my database do respond at all anymore. The queries I ran this morning seem to block all new ones.

How should I go about solving this, as my database is completely unusable at the moment. Its not in production, but if it was this would be a huge problem.
