How to use hstore

Hi all

I log data in a table using a hstore field.

My problem is that i would like to be able to retrieve a group of
records from the hstore table and present them in a grid so I would
like to convert the hstore records back to the original table format.
In the manual i found an example how to convert to a predefined record
type, exactly what i like to do but the example works great as long as
there is only one record to convert.

SELECT * FROM populate_record(null::test,
'"col1"=>"456", "col2"=>"zzz"');.

But i like to to something like this
SELECT * FROM populate_record(null::test,
(select logfield from logtable where
'"col1"=>"456" ));

So i wonder how should i do if i have lots of hstore records to
convert ? My SQl knowledge is a bit short :-)

Thank you in advance!
