Currently, ALTER TABLE ... DROP table constraint definition

Umm, put the constraint name in the table constraint definition?
From the SQL spec:<table constraint definition> ::= [ <constraint name definition> ] <table constraint> [ <constraint
attributes>]<constraint name definition> ::= CONSTRAINT <constraint name>
Currently, you need to drop the three triggers from pg_trigger
that are associated with the constraint. Easiest way to find
them if you don't have a constraint name is to look at the tg_args.
