Hi
PFA patch with following changes:
1. Extends SqlTabControl to write a new function 'onWizardChange',
instead of writing it in backform.pgadmin.js file.
Also, validations in privilegeControl are not working properly, when validations gets fixed, I will send an updated patch.
This is complete patch, as Khusboo's patch also merged in attached patch and
patches of "Sequence" and "Functions" macros are already committed.
