PostgreSQL command line cheatsheet

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)
# SYNTAX:
var pattern = new RegExp(pattern, attributes); # attributes: g (global); i (case-sensitive); m (multiline matches)
var pattern = /pattern/attributes; # same as above
# BRACKETS:
[...]: Any one character between the brackets.
[^...]: Any one character not between the brackets.
