    Sorry, forgot to add: once I get the warning that the Pg_dump

    Password:

    failed: FATAL:  p
    assword authentication failed for user "killian"

    note that databases don't have passwords, database USERS have
    passwords.  'killian' probably doesn't have a database user, and
    since you didn't specify a user, it defaulted to your system
    username (expecting that user to have been created in postgres, and
    wanting that probably non-existant postgres users passsword)

    so, ok, try the command with -U postgres, as *
    *

        *pg_dump -Fc -p 5432 **-U postgres **irll_project | pg_restore
        -U postgres -p 5532*

OK - I did the dir and it shows that the dump and restore.exe are there,
but running the above gives the below errors

09/06/2014  08:35           381,952 pg_dump.exe

09/06/2014  08:35           180,224 pg_restore.exe

C:\Users\killian>path "C:\Program Files\PostgreSQL\9.3\bin";%path%

C:\Users\killian>pg_dump -Fc -p 5432 -U postgres irll_project |
pg_restore -U po
stgres -p 5532
ccoulould not findd a n "pg_restore" to executeot find a "pg_dump" to

pg_restore: [archiver] did not find magic string in file header
pg_dump: [custom archiver] could not write to output file: Invalid argument

Try breaking the above down into two steps:

pg_dump -Fc -p 5432 -U postgres -f irll_project.out irll_project

pg_restore -U postgres -p 5532 irll_project.out

 

    if/when it prompts for a password, thats the password of the
    'postgres' database user, as configured in the postgres servers.

    note it will prompt for the password a couple times,  once for
    postgres on port 5432, and again for postgres on port 5532, at least
    if both database services are configured to require passwords for
    local connections.
