What happened?

Looks like function bodies in CREATE FUNCTION are split into multiple statements, which causes it to fail due to invalid syntax. For example

CREATE FUNCTION identity.get_random() RETURNS double precision
    LANGUAGE sql
    IMMUTABLE STRICT PARALLEL SAFE
BEGIN ATOMIC
    SELECT random();
END;

is split into 2 statements

CREATE FUNCTION identity.get_random() RETURNS double precision
    LANGUAGE sql
    IMMUTABLE STRICT PARALLEL SAFE
BEGIN ATOMIC
    SELECT random()

and

END

If the function contains multiple statements, each is split into a separate statement as well.

Relevant log output
