On re-reading I finally understood what you meant - that the
chunking applies to only standard postgreSQL TAM called "heap"

Will add that as well. Would something like work

"This flag applies only to tables that use the standard PostgreSQL
Table Access Method (TAM) called "heap".
The tables that are using any custom TAM  are dumped as if
--max-table-segment-pages was not set."
