Operator istore - int[] about istore

[chochkov]

@ArturFormella the functionality already exists as a function:

nikola@[local] nikola # \dx istore
            List of installed extensions
  Name  | Version | Schema |       Description
--------+---------+--------+-------------------------
 istore | 0.1.6   | public | an integer based hstore
(1 row)

nikola@[local] nikola # select delete('1=>0, 2=>0, 3=>0'::istore, '{2,3}'::integer[]);
  delete
----------
 "1"=>"0"
(1 row)

Oh, thank you for pointing this out!

In that case it should be really easy to add an operator, if it is helpful. I will look at this.

[rapimo]

do we finally want this as operator? What are the benefits having an operator over a function?

On further thought I think a function is clearer here than an operator (which is just semantic sugar around a function anyway). A subtraction operator might not be sufficiently clear in that case especially if you think of istore as a sparse array.
