Is there any chance the project would accept a patch which adds the
pg_stat_*_columns-feature without first optimizing the collector? I guess
it primarily depends on how much of the new code that would need to be
rewritten, if the collector is optimized/rewritten in the future?

(I would be interested in sponsoring the work, if anyone is interested.)
