URGENT TABLE PG_SHADOW CORRUTEP

help please

when I execute this query


select * from pg_shadow;


usename | usesysid | usecreatedb | usesuper | usecatupd | passwd | valuntil | useconfig

-----------+----------+-------------+----------+-----------+----------+----------+-----------

postgres | 1 | t | t | t | ******** | |

postgres | 1 | t | t | t | ******** | |

userradar | 100 | f | f | f | ******** | |

(3 rows)

the result are once tuples with the same username "postgres" but the first don´t have password. in additon, when I execute pg_dump the result is


pg_dump: saving encoding
pg_dump: saving database definition
pg_dump: SQL command failed
pg_dump: Error message from server: ERROR: more than one row returned by a subq
uery used as an expression
pg_dump: The command was: SELECT (SELECT usename FROM pg_user WHERE usesysid = d
atdba) as dba, pg_encoding_to_char(encoding) as encoding, datpath FROM pg_databa
se WHERE datname = 'radar'
pg_dump: *** aborted because of error

because there are two users with SYSID = 1, the result is in red

I have try to run this command in single user mod

select * from pg_shadow;

delete from pg_shadow;

CREATE USER postgres WITH CREATEDB CREATEUSER PASSWORD '***' SYSID 1;

CREATE USER userradar PASSWORD '***'

but the result is the same.....

thanks.....

Ayuda por favor

Cuando ejecuto este comando me sale una doble tupla del usuario postgres, esto me error cuando ejecuto el comando Pg_dump para realizar el respectivo backup..

radar=# select * from pg_user;

usename | usesysid | usecreatedb | usesuper | usecatupd | passwd | valuntil | useconfig

-----------+----------+-------------+----------+-----------+----------+----------+-----------

postgres | 1 | t | t | t | ******** | |

postgres | 1 | t | t | t | ******** | |

userradar | 100 | f | f | f | ******** | |

(3 rows)

He intentado borrar los usuario directamente de la tabla subiendo postgres com postgres -O -P -D directorio

Y corriendo estos comandos..

select * from pg_shadow;

delete from pg_shadow;

CREATE USER postgres WITH CREATEDB CREATEUSER PASSWORD '***' SYSID 1; CREATE USER userradar PASSWORD '***'

Pero me crea los mismos tres usuarios en la tabla pg_shadow, el problema es que no he podido hacer el backup y ya no tengo espacio en la particion donde tengo montada la base

Asunto: [ADMIN] trying to run PITR recovery

Hello,
I'm testing my PITR recovery procedures and something doesn't look right.
The following is from the logs upon starting postgres with recovery.conf file in place

2007-03-23 05:56:00 MDTLOG: database system was interrupted at 2007-03-18 05:09:15 MDT

@ 2007-03-23 12:14:04 MDTLOG: autovacuum: processing database "postgres"

My concern is that there were many more logfiles to be played following "00000010000011A000000FD"
(ie 000000010000011E0000005C) yet it appears the recovery stop at that point and called it good.
I would assume all WAL logs would be restored.

The recovery.conf was simple:
restore_command = 'cp /data/pgLocal/archive/WAL_restore/%f "%p"'

The backup file 000000010000011A000000EE.004E0060.backup" contained:
START WAL LOCATION: 11A/EE4E0060 (file 000000010000011A000000EE)
STOP WAL LOCATION: 11A/EFF68AB8 (file 000000010000011A000000EF)
CHECKPOINT LOCATION: 11A/EE4E0060
START TIME: 2007-03-17 20:29:16 MDT
LABEL: 076_pgdata.tar
STOP TIME: 2007-03-18 05:16:17 MDT

Does the line: incorrect resource manager data checksum in record at 11A/FD492B20
mean there is a corrupted WAL log file?

Any insight here would be helpful
version PG 8.1.2 64 bit Linux
