no particular need to do get_op_opfamily_properties() while building an indexscan plan. Postpone that lookup until executor start. This simplifies createplan.c a lot more than it complicates nodeIndexscan.c, and makes things more uniform since we already had to do it that way for RowCompare expressions. Should be a bit faster too, at least for plans that aren't re-used many times, since we avoid palloc'ing and perhaps copying the intermediate list data structure.
