Hello!

Why we don't have checksums on clog files.

We have checksum on pg_control, optional checksumming on data files, 
some form of checksumming on wal's. But why we don't have any 
checksumming on clogs. Corruptions on clogs lead to transaction 
visisbility problems and database consistency violation.

Can anybody explain this situation with clogs?
