Use homebrew to upgrade to postgres on OSX
newpg=9.6.1 # set to new PG version number
oldpg=`pg_config --version | cut -d' ' -f2`
# PG 96. upgrades the readline to v7, which breaks anything linked against readline v6, like ruby via ruby-build.
# I *think* this should prevent it from installing v7. But if weird shit happens with various rubies,
# you'll have to reinstall them.
brew pin readline
# Stop current Postgres server
brew services stop postgresql
