The reason that it needs to be rewritten in C is that it needs access to
internal stuff that the backend doesn't expose. (For example, the
transaction counter, end-of-WAL pointer, etc.) I don't think Perl would
offer anything except creating an entirely new dependency for Postgres.
Also, C code would be easier to keep in sync with the backend code that
accesses the same stuff.
