Running `gman_servers_set` in PostgreSQL's startup

I’ve compiled PostgreSQL’s gearman extension and now I can connect to a gearman server using triggers and such in PostgreSQL.

As you may know, before a job can be registered in a gearman server, you need to specify the address of your server. This is done using gman_servers_set function in PostgreSQL. I was wondering if there’s anyway I can call this function when PostgreSQL is run!?
