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)Disable vim automatic visual mode on mouse select | |

Below is an overexplained version of the following process:
~/.aws/credentials
as a "profile" which are then understood by the AWS command line tools
