Actually, I've come up with an idea just after hitting the send
button: let's use an extra ALTER TABLE SET ACCESS METHOD rather than
rely on the GUC to set the AM of the partitioned table correctly.
This extra command should be optional, depending on
--no-table-access-method. If a partitioned table has 0 as relam,
let's not add this extra ALTER TABLE at all.
