Hi Ravi,

You can use CREATE INDEX with CONCURRENTLY keyword. It will not lock your table during the process.

 I have to create a primary key on a large table (~100Million records). What is the best and fastest way to create pkey? This column is a sequence column and i don't want to lock the table because this is highly transactional database.

 Thanks
