如果您已经安装的Postgres：

尝试：

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

或者：https://stackoverflow.com/a/9669523/2670516

如果不是：

的Linux：https://stackoverflow.com/a/10792110/2670516

的Mac：

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 
source ~/.bash_profile 
pg start 
# Usage: pg {start|stop|restart|reload|status}
