I'm assuming this is a custom-format file, which is a binary file.
You need to use pg_restore to restore the file:

For example:

pg_restore -d example1 example1.dmp

This is because the file is no in plain format.  Read the
documentation for more information on the output of pg_dump:
http://www.postgresql.org/docs/current/static/app-pgdump.html

If it couldn't find the file, you'd receive an error message.

How do you know nothing happened?  Did you check the database you
loaded the file into for the objects it's supposed to create?  From
looking at the files, what do they create/insert etc?

So when you loaded the example1.dmp file into the example1 database,
did you then connect to that database and look for restored items?

How where the *.dmp files created?

Also from below you might want to use -f to designate the file:

http://www.postgresql.org/docs/9.0/interactive/app-psql.html
"
-f filename
--file filename

    Use the file filename as the source of commands instead of reading commands
interactively. After the file is processed, psql terminates. This is in many ways
equivalent to the internal command \i.

    If filename is - (hyphen), then standard input is read.

    Using this option is subtly different from writing psql < filename. In
general, both will do what you expect, but using -f enables some nice features
such as error messages with line numbers. There is also a slight chance that
using this option will reduce the start-up overhead. On the other hand, the
variant using the shell's input redirection is (in theory) guaranteed to yield
exactly the same output you would have received had you entered everything by
hand.
