Today I suggested a few things to be done with postgresql but considering my experience my interest(experience) lies in dba task mgmt and pl/pgsql code building which may not seriously fall into postgresql code contribution.
In future I may like to build indexes on json fields. Joining pgsql hackers group might need lot more expertise into c coding so respectfully I can get started with some testing activities if anyone needs some assistance while probably I could just stick to my dba tools in a personal domain.
Respectfully,
