Backup of Postgres database I want to create a backup of my database in Postgres.
I'm using pgAdmin.


on my database I have clicked right button of mouse
after that I've selected the "Create a backup of database"


After that I've got a sequence of messages:

C:\Program Files\pgAdmin III\1.12\pg_dump.exe --host localhost --port 5432 --username "postgres" --role "postgres" --no-password  --verbose --file "E:\wfr.backup" "WFR"
pg_dump: server version: 9.1.1; pg_dump version: 9.0.3
pg_dump: aborting because of server version mismatch
pg_dump: *** aborted because of error


Why didn't it create a backup and return the error instead?
pgAdmin III 1.12 does not support PostgreSQL 9.1. So better upgrade your pgAdmin III to version 1.14 or newer.
