Обсуждение: how to replicate a database from one machine to the other?
A total novice here! Machine A: Kubuntu 8.04 has the required database under user userA Machine B: RHEL 5 is the destination machine with userB I want to transfer the entire database under userA from machine A to user B under machine B. Is that possible? -- Regards PK -------------------------------------- http://counter.li.org #402424

MachineA pg_dump machineadb > madb.sql copy madb.sql across to machineB MachineB psql < madb.sql This would make a copy of the database named machineadb, if you want every db on the server then you can use pg_dumpall You may need options like -U -h and -W (username/host/prompt for password) man psql or man pg_dump for more detail Feel free to compress the file to reduce transfer times etc. You can also reduce it to one step - pg_dump machineadb | psql -h remotename -- Shane Ambler pgSQL (at) Sheeky (dot) Biz Get Sheeky @ http://Sheeky.Biz

There were some errors for missing roles, but that was expected since the usernames were different on the two machines. -- Regards PK -------------------------------------- http://counter.li.org #402424
