dumpIndex() emits ALTER INDEX .. SET STATISTICS for per-column
statistics targets, but dumpConstraint() never did. Targets set on the
expression columns of an exclusion constraint's index were silently
lost on dump/restore and pg_upgrade.
The same code can be used in the index and constraint dump code to
generate these ALTER INDEX commands. The logic has been refactored so
that both share a new subroutine in charge of generating all these
custom SET STATISTICS, if any.
