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 Jelte
