This module is expanded to track the description of the objects changed in the subcommands of ALTER TABLE by reworking the function get_altertable_subcmdtypes() (now named get_altertable_subcmdinfo) used in the event trigger of the test. It now returns a set of rows made of (subcommand type, object description) instead of a text array with only the information about the subcommand type. The tests have been lacking a lot of the subcommands added to AlterTableType over the years. All the missing subcommands are added, and the code is now structured so as the addition of a new subcommand is detected by removing the default clause used in the switch for the subcommand types. The coverage of the module is increased from roughly 30% to 50%. More could be done but this is already a nice improvement.
