Ick.  This looks *exactly* like what pg_control would contain
immediately after initdb, in a 7.4 database.  I suppose that someone
tried an initdb as a recovery method, without understanding the

No, or at least it will not improve your situation.  All those numbers
need to be higher, probably a lot higher.  See the advice in the
pg_resetxlog man page about deriving reasonable values.
