Multiple lines should not be a problem.  The problems I see are

- you won't catch DDL statements issued in a function with that, since you
  only see the top-level statement

- if you have the DDL statement as string, you need to parse it, which is
  non-trivial

In an e-mail, I cannot do much beyond pointing you to the documentation:
https://www.postgresql.org/docs/current/event-trigger-interface.html
There is also a simple example:
https://www.postgresql.org/docs/current/event-trigger-example.html

Getting used to reading and writing PostgreSQL server code takes a while.
