When trying to backup my database, the following message is presented:
my operating system is windows and I am using pgAdmin III. Someone who can help me, thank you.
You can try it from the console enter this code and change the data by your connection:
pg_dump -i -h <server> -p <puerto> -U <usuario> -F c -b -v -f <nombre_fichero> <bd>
and I leave this example of my connection that I used recently:
pg_dump -i -h localhost -p 5432 -U postgres -F c -b -v -f "/home/damian/backups/mibase.backup" mibase
This code I always use and it works well
