Jekyll & Liquid Cheatsheet

A list of the most common functionalities in Jekyll (Liquid). You can use Jekyll with GitHub Pages, just make sure you are using the proper version.

Running

Brew upgrade...

Run the usual brew update, and brew upgrade to get the latest 9.4 version of PostgreSQL.

After upgrading PG from 9.3 to 9.4 with brew, the server will not start as is. If you value your database contents, and configuration, pg_upgrade is here to migrate those.

Do not delete the old binaries at once: do not run brew cleanup, because you need 9.3 binaries to migrate.
