Hi,
In CustomScan cost estimator, where PlannerInfo and RelOptInfo are passed, I want to get access to the relation stats (for example pg_stat_all_tables) by calling pg_stat_fetch_stat_tabentry(). However, I don't have access to relid to pass to this function. For a sample relation, when I hardcode the relid (for example 16385), it works. However, RelOptInfo->relid is always 1 (for whatever relation the query is scanning). Why this happens and how to get access to the correct relid (16385) as in pg_stat_all_tables?
Thank you!
