The attached patch supports new keyword 'replication' on .pgpass file.
This keyword is used to specify the password for the standby server to
connect to the primary server.

Without this keyword, since replication doesn't correspond to the real
database, the password cannot be supplied in .pgpass file, instead,
must be specified in the conninfo string or the environment variable
PGPASSWORD.

For example, if the primary is running on host IP 192.168.1.50, port 5432,
the superuser's name for replication is foo, and the password is foopass,
the following line should be added to the .pgpass file on the standby so
that it can connect to the primary without prompting for password.

    192.168.1.50:5432:replication:foo:foopass

Thought?
