If you Read The Fine Manual
https://www.postgresql.org/docs/devel/static/index.html
I am pretty sure there's something about DDL transactibility
related to CREATE FUNCTION
https://www.postgresql.org/docs/devel/static/sql-createfunction.html
In particular, by extension, the example way at the bottom
seems relevant to your question.
