Set an option to show just short named data types, like varchar and not character varying, on grids and table column properties

Describe the solution you'd like
Set an option to show just short named data types, like varchar and not character varying, on grids and table column properties. It consumes a lot of GUI space and it is annoying... nobody use character varying, timestamp without time zone... just too long. Just use pg data type aliases, like varchar, bool, float, timetz, timestamptz, timestampt, etc... I would be even happier if timestamp became ts, date dt, varchar, vc, etc.. but just using common datatype aliases would be good.
Also updatable select datagrids should show if column is NN, currently are not.

Start by locating the grid and table column properties views that display PostgreSQL data type names, then trace how column metadata is presented. Done means an option can use common short type aliases in both areas and updatable select datagrids show whether columns are not-null; the requested aliases and option behavior still need clarification.
