The last of those is probably the easiest to get to. We already have
hstore_from_record:

contrib_regression=# select hstore(row('this', 'that'));
hstore
----------------------------
"f1"=>"this", "f2"=>"that"
(1 row)

and the only thing lacking is an easy way to specify the column names
associated with the anonymous record type. Extending the ROW()
construct with AS labels as suggested above might be a reasonable way.
