Postgresql “alter column type” creates an event which contains “temp_table_xxx”

I'm using "logical wal decoding" feature of postgresql. I've executed a
sample for data insert, update, delete operations successfully. Now I'm
trying to change my table schema like:

=> CREATE TABLE test( x varchar );CREATE TABLE=> insert into test(x)
values ('14'), ('42');INSERT 0 2=>
=> ALTER TABLE test ALTER COLUMN x TYPE integer USING
(trim(x)::integer);ALTER TABLE

Last command I've executed to alter column data type creates an event like
this:

BEGIN 500913table public.pg_temp_1077668: INSERT: x[integer]:14table
public.pg_temp_1077668: INSERT: x[integer]:42COMMIT 500913

How could I find "real" table name using this record? Is there any way to
see real table name in fetched record?

Thanks in advance.
