It works with
@raw_connection = PG.connect(dbname: local_db[:database], host: 'localhost', user: 'postgres', password: '<put your password here>', port: local_db[:port])
It’s a hard-bake but at least it goes.
I had to do following to get password set:
sudo -u postgres psql postgres
\password postgres
(enter the new password)
\q
Now onto new and interesting bugs like unique constraints (instead of copy-over)!
best,
Walker
