> *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.
