Digging a little bit more, I found that global/2676 has zero bytes, so
we restore global/ from backup.
Now the only databases we can log in the ones wich hasn´t been vacuumed
regulary, e.g. "postgres":

$ psql matriz
psql: FATAL:  cache lookup failed for database 87421438
$ psql volpato
psql: FATAL:  cache lookup failed for database 94680947
$ psql postgres
# \d
             List of relations
 Schema |      Name      | Type |  Owner
--------+----------------+------+----------
 public | pg_buffercache | view | postgres

Not sure if pg_buffercache should be there anyway ...

Ideas?
