It could be found some workarround of the problem.
Probably some key in postgres will do to use the
pg_hba.conf instead. So you will be able to connect
and
repare the problem ;).

Another solution could be some statement in
pg_hba.conf telling the postgresql to use internal
database privileges instead of this defined in
pg_hba.conf, and when the problem occurs you just
swich to the db privileges defined in pg_hba.conf.This
will make you able to connect and repare the problem
(What i meen with internal and external privileges?
OK! same as the internal and the external passwords)

The second one has some advantages: you can repare the
problem without restarting the postgresql.
