Regarding feature #6369

I have started working on Feature #6369 to add support for the syntax "ALTER TABLE ... DETACH PARTITION ... CONCURRENTLY | FINALIZE". This syntax is available from PostgreSQL v14 and above.

I have modified the old context menu item with the label 'Detach Partition' to a parent menu group with sub-menu items 'Detach', 'Concurrently', and 'Finalize'. Please refer to the below screenshots: 

v14 and Above                                                             v13 and below

                        

Let me know your thoughts/suggestions.
