.dmp files in postgresql

[Alpha Beta <dzjitaru@xxxxxxxxx>]

Hi list,

I have got two files (template1.dmp, example1.dmp) and I want to open them in postgresql, I tried the following commands: 

- Import template1 :

    * createdb -U postgres template1

    * psql -U postgres template1 < template1.dmp

- Create the sample of the database:

    * createdb -U postgres example1

    * psql -U postgres example1 < example1.dmp

I've got no error reported by postgres but nothing happened either. 

How should I proceed exactly? Sorry I'm a newbie with PostgreSQL :)

Regards!
