 Hello,

    We are using (PostgreSQL) 8.0.1 for Solaris.  Apparently our
postgres users were wiped out somehow, for I cannot even log in as
superuser "postgres".  Our pg_hba.conf settings are as loose as possible
("trust").  This problem started mid session after we ran a .sql script
to upgrade a DSpace digital library database within the postgres system.
 This action should not have affected postgres users in any way.  We did
not modify the template1 database (which affects users?) or anything of
that sort.  The only other oddity of our installation I can think of is
that fact that the local data directory (/usr/local/pgsql/data) points
to another data directory at the root of the postgres unix account which
really contains the database data (/home/local/pgsql/data).  Is there
any way to reinitialize while preserving the existing data directory
(dbinit??)?   
  
  Thanks,
Will Cameron
