Postgres版本不兼容

Question

我在启动postgres时遇到问题，如下所示：

$ pg_ctl -D /usr/local/var/postgres start
server starting
FATAL:  database files are incompatible with server
DETAIL:  The data directory was initialized by PostgreSQL version 9.1, which is not compatible with this version 9.3.0.

任何人都知道如何使这些版本兼容吗？

Answer 1

您有两种选择：

1. 运行9.1版本，转储数据库并使用9.3
恢复它
2. http://www.postgresql.org/docs/9.3/static/pgupgrade.html
