vacuumdb: Add option for analyzing only relations missing stats.
This commit adds a new --missing-stats-only option that can be used
with --analyze-only or --analyze-in-stages. When this option is
specified, vacuumdb will analyze a relation if it lacks any
statistics for a column, expression index, or extended statistics
object. This new option is primarily intended for use after
pg_upgrade (since it can now retain most optimizer statistics), but
it might be useful in other situations, too.
