I found these documents on hstore:
http://developer.postgresql.org/pgdocs/postgres/hstore.html
http://www.sai.msu.su/~megera/wiki/Hstore
From them, it seems "hstore" is another datatype (as in:
'a=>b'::hstore), which sounds good (though if it was me I'd have
picked a different name for it, like "dict" or "hashmap" :) ) for
storing both field names and their values, but I don't see a way to
convert a row/record passed to a trigger to a hstore.
