This is probably an UPDATE operation not an INSERT. There are quite a
few paths through CREATE TABLE that involve repeated updates of the
new pg_class row.
I would think however that these changes would occur as successive
commands of a single transaction, not as subtransactions, unless you've
done something odd to CommandCounterIncrement.
