Tom Lane	0ec5f7e782	Allow subscripting of hstore values. This is basically a finger exercise to prove that it's possible for an extension module to add subscripting ability. Subscripted fetch from an hstore is not different from the existing "hstore -> text" operator. Subscripted update does seem to be a little easier to use than the traditional update method using hstore concatenation, but it's not a fundamentally new ability. However, there may be some value in the code as sample code, since it shows what's basically the minimum-complexity way to implement subscripting when one needn't consider nested container objects.

Allow subscripting of hstore values.

This is basically a finger exercise to prove that it's possible for
an extension module to add subscripting ability.  Subscripted fetch
from an hstore is not different from the existing "hstore -> text"
operator.  Subscripted update does seem to be a little easier to
use than the traditional update method using hstore concatenation,
but it's not a fundamentally new ability.

However, there may be some value in the code as sample code, since
it shows what's basically the minimum-complexity way to implement
subscripting when one needn't consider nested container objects.
