There is no pretty option for this one, and the intent is for the user to
be able to input a table and trigger to get the CREATE TRIGGER statement.
Not sure how drop_first fits in here; we’re not dropping or creating
triggers.

Sorry, sometimes my fingers don't obey my brain, I wrote one thing thinking
another.
In a multi tenant world this feature will be cool for clone or sync ddl of
two schemas. So, if I’m creating a new schema the way you did works but if
both exists and I want to update some ddls of a schema, sometimes I have to
DROP and CREATE or returned command should have CREATE OR REPLACE,
depending on what ddl you are doing.
If you try to create a trigger but it already exists, you’ll get an
exception, so you can emit a DROP IF EXISTS before CREATE of that trigger.
For this that param drop_first would be.
I know you are doing only trigger ddl rigth now but I think we would have
this kind of functions for tables, constraints, triggers, domains and so
on, then all of them should work the same way, and for this a drop_first or
if_exists would be good.
