| psql -U postgres // start postgres shell or command line interface. | |
| Some interesting flags (to see all, use -h or --help depending on your psql version): | |
| -E: will describe the underlaying queries of the \ commands (cool for learning!) | |
| -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS) | |
| Most \d commands support additional param of __schema__.name__ and accept wildcards like *.* | |
| \q: Quit/Exit | |
| \l list all the databases | |
| \c __database__: Connect to a database |
