I thought I had already posted this query but now I can't remember.  If
I have please excuse the repeat.  But as I can't remember the answer
either can someone please comment.

Is there likely to be any attempt to allow a table to be keyed.  It
seems that by default a table is created as a heap and in order to
improve access speed, one must create indices on that table.

I use Ingres at work and quite like the ability to do a 'modify table to
btree' type of command.  When the table concerned is basically only a
key plus value, it seems rather inefficient to have to have both the
heap and then an index when supposedly one could simply make the table
into a btree in the first place.
