tableam: Add pg_dump support.
This adds pg_dump support for table AMs in a similar manner to how
tablespaces are handled. That is, instead of specifying the AM for
every CREATE TABLE etc, emit SET default_table_access_method
statements. That makes it easier to change the AM for all/most tables
in a dump, and allows restore to succeed even if some AM is not
available.
This increases the dump archive version, as a tables/matview's AM
needs to be tracked therein.

This or a nearby patch broke cross-version pg_upgrade, according to the
buildfarm.

Yea, I started a thread about it: https://www.postgresql.org/message-id/20190306204104.yle5jfbnqkcwykni%40alap3.anarazel.de In short, I think this was basically not this patch's fault, it just added an assertion that coincidentally triggered for the changes in https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=807ae415c54628ade937cb209f0fc9913e6b0cf5 et al. When pg_upgrading from pre v12, we're creating a partitioned table that doesn't have a relfilenode, but does have a toast table. Greetings, Andres Freund
