echo "alias pg='pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log'" >> ~/.bash_profile
source ~/.bash_profile

brew install postgresql
initdb /usr/local/var/postgres -E utf8
# Add PostgreSQL to launchctl to let OS X manage the process and start when you login
ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
echo "alias pg='pg_ctl -D /usr/local/var/postgres -l /usr/local/var/postgres/server.log'" >> ~/.bash_profile
