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
