Re: psql: FATAL: database "postgres" does not exist or ERROR: 23505: duplicate key value violates unique constraint "pg_namespace_nspname_index"

Thanks Denial,

Already I tried to connect with template0, template1, user database name,
postgres, nothing is working getting same error message as mentioned in
trail mail.

For the second one, yes we don't have backups to restore, we don't have any
option apart from data directory(no wal files)

Regards,
Narresh
