Default JDBC introspection for index metadata on the JdbcConnection. This is currently used for migrations by JdbcSpec::HSQDLB and JdbcSpec::Derby indexes with a little filtering tacked on.
JDBC index metadata is denormalized (multiple rows may be returned for one index, one row per column in the index), so a simple block-based filter like that used for tables doesn‘t really work here. Callers should filter the return from this method instead.
