Mark default_transaction_read_only as GUC_REPORT. This allows clients to find out the setting at connection time without having to expend a query round trip to do so; which is helpful when trying to identify read/write servers. (One must also look at in_hot_standby, but that's already GUC_REPORT, cf bf8a662c9.) Modifying libpq to make use of this will come soon, but I felt it cleaner to push the server change separately.
