Commit 325f2ec555 introduced pg_class.relwrite to skip operations on tables created as part of a heap rewrite during DDL. It links such transient heaps to the original relation OID via this new field in pg_class but forgot to do anything about toast tables. So, logical decoding was not able to skip operations on internally created toast tables. This leads to an error when we tried to decode the WAL for the next operation for which it appeared that there is a toast data where actually it didn't have any toast data. To fix this, we set pg_class.relwrite for internally created toast tables as well which allowed skipping operations on them during logical decoding.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
