Clarify docs about database parameter in streaming replication primary_conninfo.

Docs were unclear on whether or not database=replication was required,
nor did they mention the FATAL error this causes if database parameter is
mentioned explicitly, whatever its value.

+      You do not need to specify database=replication in the
+      primary_conninfo. The required option will be added
+      automatically. If you mention the database parameter at all within
+      primary_conninfo then a FATAL error will be raised.
