Álvaro Herrera c2da1a5d63 Make query jumbling also squash PARAM_EXTERN params ... Commit 62d712ecfd made query jumbling squash lists of Consts as a single element, but there's no reason not to treat PARAM_EXTERN parameters the same. For these purposes, these values are indeed constants for any particular execution of a query. In particular, this should make list squashing more useful for applications using extended query protocol, which would use parameters extensively. A complication arises: if a query has both external parameters and squashable lists, then the parameter number used as placeholder for the squashed list might be inconsistent with regards to the parameter numbers used by the query literal. To reduce the surprise factor, all parameters are renumbered starting from 1 in that case.
