Thanks Robert, but I cant get from PostgreSQL server to the Cache Server thats why I need to export the data, but this information help me with another problem.

Thanks a lot.

Hi Evgeny, I dont know if this exist on cache, but on PostgreSQL you can export the data as SQL format (on a dump file). 

And I was thinking there is maybe a way to export data from cache as this format (SQL format).

This exists on Cache? 

Thanks and sorry for the delay to answer.

Thanks a lot for the informations, its works for me.

How do you get all the informations about this classes? there is any link to get this info ?
