		<description>Hi,
如果用postgres这个用户init数据库的时候就不需要指定D参数了
你应该用su - postgres来切换用户 这样用户的变量也才会跟着切换，不带-的切换是无效的
  -, -l, --login               make the shell a login shell, 
                               clears all envvars except for TERM,
                               initializes HOME, SHELL, USER, LOGNAME and PATH</description>
