Hi guys. I'm writing about somethings of Postgresql. In first place, this database allow me to make an on-line backup?.

And the other, I'm working in Spanish so I have defined a table field named 'Nombre'(Name) and try to put in a record a word on this field: 'Jóvenes' (Youngs) but when I the value I have 'J?venes'. So the INSERT change me the character 'ó' by '?'. I don't understand this change so if anyone can give me a tip, please.

Regards.
