I try translated the mesages.po file into Polish, but I don't know how to send it for use in the project.
I thought I should make a Pull request on github, but I read "Mirror of the pgAdmin 4 GIT repo. DO NOT submit pull requests here! Use the pgadmin-hackers@lists.postgresql.org mailing list."
I would be grateful if someone from the pgAdmin team would take a look at the file.
