PostgreSQL 11.2 has been running properly inside a Docker container until I did a docker-compose up to start a new container for another app, then accidentally press Ctrl+C, which killed all the running containers including the one containing PostgreSQL named timescaledb.

When I tried to start PostgreSQL again using the command docker-compose up -d, the docker log files show the following messages, including the errors

unexpected file found in temporary-files directory

and

database system was interrupted; last known up at 2020-02-13 03:13:42 UTC

Do we need to do anything to the unexpected temporary files?

If you make sure that there is no query running on the database currently that may be using a temporary file, it is safe to remove these leftovers.
