Hi @anothername : I did not use the "restore" button. To restore database quickly, you should use psql in Terminal (Menu > Laragon > Terminal). The command is simple:
psql my-database < path-of-my.sql
PostgreSQL is secure in local (with
pg_hba.conf), so you can login with no password with 2 users:
Your-Windows-Account(Laragon automatically creates it)
Once you use PostgreSQL with Laragon, you'll find it is very easy to manage.
