The service discovery feature allows back ends to automatically find the
5
appropriate servers to connect to using a special DNS query.

10
If no servers are specified, the back end automatically uses service
11
discovery to try to find a server. Optionally, the user may choose to use
12
both fixed server addresses and service discovery by inserting a special
13
keyword, <quote>_srv_</quote>, in the list of servers. The order of
14
preference is maintained. This feature is useful if, for example, the user
15
prefers to use service discovery whenever possible, and fall back to a
16
specific server when no servers can be discovered using DNS.
