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)

# DigitalOcean: this file was written via cloud-init and composed from /etc/cloud/cloud.cfg
#               In order to support resize events, 'growpart' and 'resizefs' are run each boot.
#               'update_etc_hosts' will be run only once per instance. To see the differences, run
#               'diff -u /etc/cloud/cloud.cfg /etc/cloud/cloud.cfg.d/90-digitalocean.cfg'.

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
