[Dovecot] example sql acl_shared_dict wiki

Hi Timo, wiki says

Shared mailbox listing .....

You could use any dictionary backend, such as SQL or Berkeley DB, but a simple flat file should work pretty well too:

plugin { acl_shared_dict = file:/var/lib/dovecot/shared-mailboxes.db } ....

could you include an example for having acl_shared_dict in sql ?
