Re: Add table access method as an option to pgbench

Hello David,

Some feedback about v4.

Hmmm. If you take the resetting the default, I do not think that you
should have to test anything? AFAICT the access method is valid on
partitions, although not on the partitioned table declaration. So I'd say
that you could remove the check.

I think it is pretty unlikely that someone would chose the name
"no-such-table-am" when developing a new storage engine for Postgres
inside Postgres, so that it would make this internal test fail.

There are numerous such names used in tests, eg "no-such-database",
"no-such-command".

So I'd suggest to add such a test to check for the expected failure.

Yep, only "heap" if currently available for tables.
