There's a mismatch between what hstore provides (schemaless key/value
storage) and what WFS provides (schema-tied attribute access). You
can't easily public schemaless data via WFS. As another response
points out, you can design a SQL query that maps keys in your hstore
into output attributes and then MapServer/WFS can happily publish
them, but in that case you might also have been better served by just
having those keys as columns in your table.
