PSQL

Magic words:

psql -U postgres

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)

If you are using bash, ash, ksh or some other Bourne-style shell, you can add ABC="123"; export ABC in your .profile file (${HOME}/.profile). This is the default situation on most unix installations, and in particular on Debian.
If your login shell is bash, you can use .bash_profile (${HOME}/.bash_profile) or .bash_login instead.
