Big +1, this is a great addition!
I think it would be very useful if there were some tests for this new
feature. Something similar to the tests for storage parameters for
index AMs in src/test/modules/dummy_index_am.
Apart from that I think the documentation for table storage parameters
needs to be updated in doc/src/sgml/ref/create_table.sgml. It now
needs to indicate that these parameters are different for each table
access method. Similar to this paragraph in the create index storage
parameter section of the docs:
> Each index method has its own set of allowed storage parameters.
> The B-tree, hash, GiST and SP-GiST index methods all accept this
> parameter
