问题
My mac has postgresql 10.1 on it, and I need 9.6 for my work website to function on my local machine. Can't find easy instructions on how to uninstall or downgrade to 9.6. Any help would be appreciated!

I got this issue as well after running brew upgrade. Following commands worked for me:
brew uninstall postgresql
brew install postgresql@9.6
brew services start postgresql@9.6
brew link postgresql@9.6 --force
