Is there a way to determine the adapter type, as well as, other
information on the fly for a database? For example, can you make a
generic type connection to a database (assuming the db server port
and/or credentials are correct) and ask the db information about itself,
then based on the response configure the establish_connection
accordingly? The initial generic connection would not access the actual
data for ROR, but determine the information about the DB for use with
ROR.
One approach is to attempt to access the DB cycling through the
available adapter types until you get a response, however, this seems
clunky at best.

You probably could - tools like nmap can probably tell the difference
between mysql running on port x, postgresql running on that same port
etc...
It seems like quite a lot of effort for a onetime setup job though
(unless you're very focussed on that wow it works straight out of the
box experience)
