utilities to rebuild commit logs from wal
Before we reinvent the wheel here, does anyone know of utilities to build
commit logs from wal segments? Or even to just fill with commits?
I figure it is worth asking before I write one.

I was missing pg_xact segments and wanting to rebuild them following a
major filesystem crash.
I ended up just writing copying in "all commits" because rollbacks were
very rare on these dbs. I am still curious if there is an easy way if one
is missing a late segment to generate from WAL if enough WALs are stored
and the WAL level is high enough.
It's not the end of the world but this has helped me to get data about 10
hours more recent than latest backup. So.... so far so good.
