Move database from one server to another
Hey Mats,
If you go for option 1, something like this:
Launch program pg_dump -d=databasename -h=ipaddress -U=backupuser
-f=mybackup.backup << password (Do not quit Omnis)
or
Start program normal {pg_dump -d=databasename -h=ipaddress -U=backupuser
-f=mybackup.backup << password}
Just need to add paths probably and make sure pg_dump is included with
you install.
Cheers,
Bas
