This should not really be @databasename, but rather a @domainname as
Mark does in fact want to use the same user from some virtual host
(==domain) for more than one database sometimes.

Using databasename as a domainname is just the quickest way to resolve
the domainname if no more info about it is given.

Thinking of the @xxx part as a domainname and not tying it to
databasename would be beneficial in case we later want to use other
kinds of domains (like NT, DNS/mail, YP or Kerberos domains for example)

If need arises we could later split out the @xxx part to "usedomain"
field and perhaps also add "usedomainkind" field in order to manage that
info in databse instead of pg_hba.conf.
