Converting an hstore into a key/value record

[Jon Smark <jon.smark@xxxxxxxxx>]

Hallo,

Suppose I have the following 'scores_t' record:

  create type scores_t as (item text, score int);

What's the cleanest way of converting a hstore into a set of scores_t,
with each key mapping to field 'item', and the value to field 'score'?

As an example, consider the following (non-working) code:

  create table people (id int4 unique not null, scores hstore);

  create function get_scores (int4)
  returns setof scores_t
  language sql stable as
  $$
        select each (scores) from people where id = $1;
  $$

Sure, I could cook up some PL/pgSQL to do this task, but I suspect
there must be some much simpler SQL statement that does the same...

Thanks in advance!
Jon
