升级Homebrew中的PostgreSQL

最后还是入手了新版的MBP，开发环境都是重新设置的，用PostgreSQL的时候，启动提醒版本不兼容

FATAL:  database files are incompatible with server
DETAIL:  The data directory was initialized by PostgreSQL version 9.5, which is not compatible with this version 9.6.2.

所以要升级一下原来的库，作弊条开始

brew services stop postgresql
brew install [email protected]
initdb /usr/local/var/postgres9.6 -E utf8
开始升级数据库

pg_upgrade \
  -d /usr/local/var/postgres \
  -D /usr/local/var/postgres9.6 \
  -b /usr/local/Cellar/[email protected]/9.5.6/bin \
  -B /usr/local/Cellar/postgresql/9.6.2/bin/ \
  -v

mv /usr/local/var/postgres /usr/local/var/postgres9.5
mv /usr/local/var/postgres9.6 /usr/local/var/postgres
brew services start postgresql

完成
