It looks OK to me, but just two things:
1) Isn't it better to name "CheckSchemaPublication" as
"IsSchemaPublication", since it has a boolean return and also
typically CheckXXX type functions normally do checking and error-out
if they find a problem.
2) Since superuser_arg() caches previous input arg (last_roleid) and
has a fast-exit, and has been called immediately before for the FOR
ALL TABLES case, it would be better to write:
+ if (CheckSchemaPublication(form->oid) && !superuser_arg(newOwnerId))
as:
+ if (!superuser_arg(newOwnerId) && IsSchemaPublication(form->oid))
