In the custom stored function, I'm returning a resultset using hstore
function.
RETURN QUERY SELECT a few other columns, hstore(t.*) FROM table t WHERE
condition.

I don't want to change it to

SELECT a few other columns, hstore('c1', CAST(t.c1 AS TEXT)) ||
hstore('c2', CAST(t.c2 AS TEXT)) || ...hstore('cn', t.cn::text) || ... FROM
table t WHERE condition.
