Subject: Since createplan.c no longer cares whether index operators are lossy,
 it has 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.
