Postgresql语法错误在或附近＆＃34; pg_ctl＆＃34;

Question

当我在运行postgresql版本9.4.11的远程服务器上运行命令 pg_ctl status 时， 我收到此错误消息：

{ [error: syntax error at or near "pg_ctl"]
  name: 'error',
  length: 87,
  severity: 'ERROR',
  code: '42601',
  detail: undefined,
  hint: undefined,
  position: '1',
  internalPosition: undefined,
  internalQuery: undefined,
  where: undefined,
  schema: undefined,
  table: undefined,
  column: undefined,
  dataType: undefined,
  constraint: undefined,
  file: 'scan.l',
  line: '1053',
  routine: 'scanner_yyerror' }

如果服务器已启用，我想获取信息。
