Well, there exist such things as SRV records already for describing how
to find services. In theory you could create an entry like:

_postgres._tcp.example.com  SRV  10 5 5432 db1.example.com

So that if you typed "psql example.com" it would lookup the server and
port number. You may be able to put a dbname after that, not sure. And
you can always put whatever you like into a TXT record.

In any case, someone still needs to write the code for it.

Have a nice day,
