Hi,
When I execute the following query:
SELECT 'a=>1'::hstore ? 'a'::text
I get an "Input parameter count is less then expected" error message.
SELECT defined('a=>1'::hstore, 'a'::text) -- works
I have tried on Linux Ubuntu (9.2.1) and Windows 7 (9.2.2) machines.
My knowledge and experience with the system catalogs is limited so if you
need additional information please be specific.
Thanks!
Dave
