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)

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

1) Create a branch with the tag
	git branch {tagname}-branch {tagname}
	git checkout {tagname}-branch

2) Include the fix manually if it's just a change .... 
	git add .
	git ci -m "Fix included"
    or cherry-pick the commit, whatever is easier
	git cherry-pick  {num_commit}
