I simplified the code largely by moving the logic of reading the WAL
buffer page from a separate function to the main while loop. This
enabled me to get rid of XLogReadFromBuffersGuts() that v5 and other
previous patches have.

Please find the attached v6 patch set for further review. Meanwhile,
I'll continue to work on the review comment raised upthread -
