+    If two arguments are present, the first is first assumed to be a specific
+    connection name to use. If the name is not found, the argument is then
+    assumed to be a valid connection string, of standard libpq format,
+    e.g.: "hostaddr=127.0.0.1 dbname=mydb user=postgres password=mypasswd"
 
-    standard libpq format connection string, 
-    e.g. "hostaddr=127.0.0.1 port=5432 dbname=mydb user=postgres password=mypasswd"
-    If the second form is used, then the dblink_connect(text connstr) must be
-    executed first.
+    If only one argument is used, then the unnamed connection is used.
