Amit, thanks for rebasing this patch. I already had a similar rebased patch in
my local tree. A recent patch broke your version v15 so I rebased it.

I like the idea of a simple create_estate_for_relation() function (I fixed an
oversight regarding GetCurrentCommandId(false) because it is used only for
read-only purposes). This patch also replaces all references to version 14.

Commit ef948050 made some changes in the snapshot handling. Set the current
active snapshot might not be required but future changes to allow functions
will need it.

As the previous patches, it includes commits (0002 and 0003) that are not
intended to be committed. They are available for test-only purposes.
