# To determine what dconf keys and values to use, you can run `dconf watch /`
# in a terminal as you make changes in settings or tweaks. You can also use
# `dconf read <key>` and `dconf write <key> <value>` to experiment with various
# settings. The dconf-editor application is also useful for exploring various
# keys along with their descriptions.

PostgreSQL command line cheatsheet


Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):
