FAQ
Hi there,

I have been having problems using the pg_dumpall function. I am trying to
dump all the information on my database onto a file or view it. Actually
what am trying to achieve is by using the pg_dumpall i can view dead rows
once the db has been dumped into a file. I had a look online and tried to
run the pg_dumpall command from dos using this code:

pg_dump Test > aaron.db

but came up with this error:

C:\Program Files\PostgreSQL\9.0\bin>pg_dump Test > aaron.db
Password:
pg_dump: [archiver (db)] connection to database "Test" failed: FATAL:
password
authentication failed for user "Enabs"

test being the name of the database and aaron.db being the output file
wanted it to view
again am sure you might think the password authentication failed due to
password, but changed the password, tried again and still no success..

If anyone can link me to a video or example on how the pgdump works or how
to use it, i would be very grateful. Thanks

    Try specifying the username and password with the command. I think it might not like the user name, it is case sensitive.

    pg_dump --username=USER --password=PASS Test > aaron.db

    hi thanks for that i tried it but still same error:

    C:\Program Files\PostgreSQL\9.0\bin>pg_dump --username=postgre
    --password=1234 Test > aaron.db
    Password:
    pg_dump: [archiver (db)] connection to database "Test" failed: FATAL:
    password
    authentication failed for user "postgre"

    Once i press enter it asks for the password again which i enter as the
    password above but get the same error message.

    The root username should be "postgres".

    Are you able to connect using psql or PgAdmin?

    I have just uninstalled postgresql version 9 and would install version 7 to
    carry out my research. I have not used or installed psql or pgadmin on my
    machine, as i was advised my project just required a database and nothing
    much. What am trying to do is by using pg_dumpall i could display or dump
    dead rows or all rows into a file and locate dead rows from that.

    Cheers
