Rename of functions with same name but different signatures

[clrgit]

Summary

The @name smarttag doesn't seems to work when renaming functions with the same name but different signatures

Version 4.12.11

Steps to reproduce

The following code demonstrates the problem:

drop function if exists func(integer);
drop function if exists func(integer, integer);

create function func(i integer) returns integer as $$
  select i
$$ language sql;

create function func(i integer, j integer) returns integer as $$
  select i + j
$$ language sql;

comment on function func(integer) is E'@name func1';
comment on function func(integer, integer) is E'@name func2';

Expected results

When creating a new mutation, I would expect the renamed functions 'func1' and 'func2' to show up in GraphiQL

Actual results

Neither the renamed functions nor the original functions are available in GraphiQL

This seems to be an issue in V5 also.
