Welcome!

Personally I prefer Vim. Sublime Text and Visual Studio Code are fine too.
> 2. What version control do you use for postgres? Is github acceptable?
Github is OK.

Vim + Ctags. Editors like Sublime Text and Visual Studio Code have
features like "goto definition" out-of-the-box.
If you have any other questions please don't hesitate to ask!
