I am ok with the name.

I thought we wanted to avoid having to add this setting in individual
regression tests. Can't we do this in pg_regress as a common setting ?

So this will make psql hide the access method if it's same as the
default. I understand that this was kind of concluded in the other
thread "Displaying and dumping of table access methods". But IMHO, if
the hide_tableam is false, we should *always* show the access method,
regardless of the default value. I mean, we can make it simple : off
means never show table-access, on means always show table-access,
regardless of the default access method. And this also will work with
regression tests. If some regression test wants specifically to output
the access method, it can have a "\SET HIDE_TABLEAM off" command.
If we hide the method if it's default, then for a regression test that
wants to forcibly show the table access method of all tables, it won't
show up for tables that have default access method.

If the server does not support relam, tableinfo.relam will be NULL
anyways. So I think sversion check is not needed.
------------
+ printfPQExpBuffer(&buf, _("Access method: %s"), fmtId(tableinfo.relam));
fmtId is not required. In fact, we should display the access method
name as-is. fmtId is required only for identifiers present in SQL
queries.
-----------
+ printfPQExpBuffer(&buf, _("Access method: %s"), fmtId(tableinfo.relam));
+ printTableAddFooter(&cont, buf.data);

}
Last two blank lines are not needed.
-----------
+ bool hide_tableam;
} PsqlSettings;
These variables, it seems, are supposed to be grouped together by type.

I believe you are going to add a new regression testcase for the change ?
