Speed Up Mission Control Animations in MacOS Sierra:
defaults write com.apple.dock expose-animation-duration -float 0.1
// and restart Dock with "killall Dock"
// Go back to default speed:
defaults delete com.apple.dock expose-animation-duration; killall Dock

Set Key Repeat:
defaults write -g InitialKeyRepeat -int 10 # normal minimum is 15 (225 ms)
defaults write -g KeyRepeat -int 1 # normal minimum is 2 (30 ms)
// login/logoff is neded

psql -U postgres

If run with -E flag, it will describe the underlaying queries of the \ commands (cool for learning!).

Most \d commands support additional param of __schema__.name__ and accept wildcards like *.*
