Another point I didn't raise first time around, but that's IMO quite
significant, is that you haven't addressed why this approach to fully
parallel seqscans is useful and solves real problems in effective ways.
It might seem obviou

Sorry for not being clear, Yes it is parallel sequential scan.

I think you mean "Parallel Sequential Scan".
Scanning a sequence in parallel doesn't make much sense.

Corrected subject.
Hi Hackers,
Implementation of "Parallel Sequence Scan"
Approach:
1."Parallel Sequence Scan" can achieved by using the background
workers doing the job of actual sequence scan including the
qualification check also.
2. Planner generates the parallel scan plan by checking the
