我在系统更新后收到此消息:
unrecognized configuration parameter "custom_variable_classes" in file "/var/lib/pgsql/data/postgresql.conf" line 501
解决方法
从版本9.2开始,不再需要此声明:
http://www.postgresql.org/docs/current/interactive/release-9-2.html#AEN111020
只需删除或取消注释该行:
#custom_variable_classes = 'foo' # list of custom variable class names foo.bar=0
