emqx_auth_pgsql插件启动失败，为什么？

[leqii-com]

错误提示：
Load plugin emqx_auth_pgsql error: {emqx_auth_pgsql,
{bad_return,
{{emqx_auth_pgsql_app,start,[normal,[]]},
{'EXIT',
{{badmatch,
{error,
{shutdown,
{failed_to_start_child,
emqx_auth_pgsql,
{shutdown,

{failed_to_start_child,

invalid_authorization_specification}}}}}}}},
[{emqx_auth_pgsql_app,start,2,
[{file,"emqx_auth_pgsql_app.erl"},
{line,37}]},
{application_master,start_it_old,4,
[{file,"application_master.erl"},
{line,277}]}]}}}}}.
为什么emqx_auth_pgsql插件启动不了？
