All you asked were pg related questions and it is infact a general question mailing list.
I do not feel it is right to do name calling like this in the entire public mailing list. I would have ignored the replies as well, but I am only replying so that no one feels intimidated and stop asking questions due to those replies.
Why is it so hard to ignore a query if it is so basic. let others who have enough free time, ( Yes I have no job so all the free time n the world I keep looking for queries, discussions on the telegram , irc and mailing list and if I can learn something new while trying to help someone. I consider it win win)
