# Bacula interface to mtx autoloader
#
# Created  OCT/31/03 by Alexander Kuehn, derived from Ludwig Jaffe's script
#
# *Heavily* hacked between 31/10/07 & 02/11/07 by Sean Cardus to make it work
# with the current Bacula version & our LTO tape drive.  This works for me,
# it might work for you too - But, don't blame me if it blows up :)

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

• -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)
