Hi All ,

 I found the below reference leak on master.

Steps to reproduce the issue :
--1) create type
create type float_array_typ as ( i float8);

--2) create anonymous block
postgres=# do $$
 declare
  a float_array_typ[];
 begin
  a[1].i := 11;
  commit;
 end
$$;
WARNING:  TupleDesc reference leak: TupleDesc 0x7ff7673b15f0 (16386,-1)
still referenced
ERROR:  tupdesc reference 0x7ff7673b15f0 is not owned by resource owner
TopTransaction
postgres=#

*Regards,*
Rohit
