我在我的Ubuntu机器上安装了Postgresql 9.1和9.2.
postgresql服务启动两个版本：
$sudo service postgresql start $* Starting Postgresql 9.1 database server [ OK ] $* Starting Postgresql 9.2 database server [ OK ]
我想启动9.2服务器,但没有卸载9.1,这可能吗？
精简版：
在/etc/postgresql/9.1/main/start.conf中将auto替换为manual
在/etc/postgresql/9.1/main/start.conf中将auto替换为manual
长版：
Debian / Ubuntu中的每个Postgresql集群都有一个start.conf文件,用于控制/etc/init.d/postgresql应该执行的操作.
这与pg_createcluster一起记录：
STARTUP CONTROL
The start.conf file in the cluster configuration directory controls the
start/stop behavior of that cluster’s postmaster process. The file can
contain comment lines (started with ’#’),empty lines,and must have
exactly one line with one of the following keywords:
auto
The postmaster process is started/stopped automatically in the init
script. This is also the default if the file is missing.
manual
The postmaster process is not handled by the init script,but
manually controlling the cluster with pg_ctlcluster(1) is
permitted.
disable
Neither the init script nor pg_ctlcluster(1) are permitted to
start/stop the cluster. Please be aware that this will not stop the
cluster owner from calling lower level tools to control the
postmaster process; this option is only meant to prevent accidents
during maintenance,not more.
