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)

Netrw Cheatsheet (Vim's File Browser)

See also:

• vinegar.vim, which makes - open netrw in the directory of the current file, with the cursor on the current file (and pressing - again goes up a directory). Vinegar also hides a bunch of junk that's normally at the top of netrw windows, changes the default order of files, and hides files that match wildignore.

  With vinegar, . in netrw opens Vim's command line with the path to the file under the cursor at the end of the command. ! does the same but also prepends ! at the start of the command. y. copies the absolute path of the file under the cursor. ~ goes to your home dir. Ctrl+6 goes back to the file (buffer) that you had open before you opened netrw.

To launch netrw:

wez

" Wez's VIM colors for Dark background
" vim:ts=2:sw=2:et:

hi clear
if exists("syntax on")
  syntax reset
endif
let g:colors_name = "wez"
let &background="dark"
