On first index creation (block directory is created) and only that time all columns are scanned. Later any index creation just scans needed columns. cherry-picked. Note influence of greenplum-db/gpdb-archive@8c92aa0
We can get indexes for blkdir and visimap from pg_index via `RelationGetIndexList`. Removing these 2 fields will reduce catalog size. Basically, we now deal with these two properties in a more similar way as the indexes of toast tables, where we always open the toast table first and then get its index via `RelationGetIndexList`. In fact, in majority of the places currently we already have those two aux tables opened. The only place we didn't is in ATExecSetTableSpace(), but it shouldn't slow down that function too much anyway. The other notable thing is that we need to modify how we get these indexes in pg_dump - we now have to check the pg_index.

While working on issue #989 I realized we need to cherry-pick a couple of valuable contributions from GP7 to resolve diff easily. Also, there is a benefit of cherry-picking catalog-changing contributions before CBDB 2.0 release.
