Hi Kuntal,

Thanks for the patch.

Current patch has no docs, no tests and no explanatory comments, so
makes review quite hard.

The good news is you might discover a few bugs with it, so its worth
pursuing actively in this CF, though its not near to being

I think you should add this as part of the default testing for both
check and installcheck. I can't imagine why we'd have it and not use
it during testing.

What does this mean? (No docs)

We probably need to have a discussion as to why you think this should
be Rmgr dependent?
Code comments would help there.

If it does, then you should probably do this by extending RmgrTable
with an rm_check, so you can call it like this...


I'm interested in how we handle the new generic WAL format for blocks.
Surely if we can handle that then we won't need an Rmgr dependency?
I'm sure you have reasons, they just need to be explained long hand -
don't assume anything.

Why not do this first?

There are some coding guideline stuff to check as well.
