Trigger functions should not contain references to database operations. Perhaps the trigger implements ensuring some invariant of the operation but it does not implement the operation itself.
Notes
The query assumes that database operations are in the form OP. In the returned body of routine the query replaces each newline character with the line break (br) tag for the better readability in case the query result is displayed in a web browser. There could be multiple routines with the same name but with different parameters in the same schema (overloading). Thus, for the unique identification of the routine it is necessary to present also its parameters in addition to the schema name and routine name.
Type
Problem detection (Each row in the result could represent a flaw in the design)
Remove references to the database operation from the comment.
