> *WALPrettyPrinter* is very useful for troubleshooting wal issues, such as 
> faulty replication sinks. An useful information one might want to track is 
> the size of a single WAL entry edit, as well as size for each edit cell. Am 
> proposing a patch that adds calculations for these two, as well an option to 
> seek straight to a given position on the WAL file being analysed.
