What is more, the changes done for parallel pg_restore actually did some
of the requisite work of classifying members, as can be seen in this
definition in pg_dump.h:
typedef enum _teSection
SECTION_NONE = 1, /* COMMENTs, ACLs, etc; can be
SECTION_PRE_DATA, /* stuff to be processed before data */
SECTION_DATA, /* TABLE DATA, BLOBS, BLOB COMMENTS */
SECTION_POST_DATA /* stuff to be processed after data */
Of course, you'd need to figure our how to handle the SECTION_NONE
entries, but other than that it should be pretty simple, I think.
