I don't think that the database-specific xl_running_xacts WAL record affects
what SnapBuildSerialize() writes to disk: the contents of builder->committed,
etc. is updated by decoding COMMIT and ABORT records.

On the other hand, with that kind of record, there's probably no reason to
call SnapBuildSerialize(). Good catch, thanks.
