A result set is updatable if:
* All the columns belong to the same table.
* All the primary keys or OIDs of the table are explicitly selected.
* No columns are duplicated.
* All columns are either selected directly from a single table, or
are not table columns at all (e.g. concatenation of 2 columns).
Only columns that are selected directly from the table are

Any columns that are renamed or selected more than once are also read-only.
Editable and read-only columns are identified using pencil and lock icons
