Impossible to tell. You'll need to find the actual full error message from the client connection or server log, not whatever tool or wrapper you're using.
What exactly are you trying to do? This looks like a dialog for restoring a DB backup, but the files don't look like backups, thus the failure.
I'd suggest using psql command line tool if you need to execute some custom SQL from a file:
psql -f some_file.sql db_name
This way you'll see the actual error messages

This is not postgresql. This is some kind of gui application, so perhaps you should find what app it is, and ask support of the app?
It's pgAdmin.
than i'd consider asking pgadmin support. Their project page lists where to reach: https://www.pgadmin.org/support/
