# On production
sudo -u postgres pg_dump database | gzip -9 > database.sql.gz

# On local
scp -C production:~/database.sql.gz
dropdb database && createdb database
gunzip < database.sql.gz | psql database

Unfortunately, homebrew does not support --with-universal-ctags option for global (on the state of April 2018) The reason is that universal-ctags is not officially released yet.

Install universal ctags

Run brew install --HEAD universal-ctags/universal-ctags/universal-ctags (See https://github.com/universal-ctags/homebrew-universal-ctags repo)

If you're on macOS, you might have an old ctags installed with command line tools for XCode. To fix this, simply run alias ctags="brew --prefix/bin/ctags"
