And the bigger question, Where are the missing 180G ?
In the toaster probably...
Basically large data values are store in another table different than both the
main table and indexes.
The query also says C.relkind <> 'i' which means it’s excluding indexes. Also
note that pg_catalog is excluded but LOB data would be stored in
pg_catalog.pg_largeobject. That could account for some overlooked space as
