This would require capture of information beyond what I was thinking
about in terms of schema. Do you think we need to capture just index
type, or something more? Do you propose that we capture the pg_*
metadata related to every object referenced in the plan, every object
related to every table in the query, or everything in the entire
database?

the only way you're going analyze index costing by type
of index is if the index name is stored somewhere (db_object) so that it
can be matched to its characteristics.
