This gist I write, because I couldn't find step by step instructions | |
how to install and start postgresql locally (using conda within a conda environment - with the result | |
that you can run it without sudo/admin rights on your machine!) | |
and not globally in the operating system (which requires sudo/admin rights on that machine). | |
I hope, this will help especially people new to postgresql (and those who don't have sudo/admin rights on a specific machine but want | |
to run postgresql there)! | |
