What does the shell command: pwd show when run immediately after you issue a su postgres command?
You may want to try su - postgres to ensure you are in the postgres users home directory.

Dear all,
I'm trying to dump my database using the following command after I enter as su postgres:
pg_dump - U postgres mydb -f mydb.sql
... but I'm always having the following message:
pg_dump [archiver] Could not open output file "mydb.sql" : Permission denied
I try to use the same statement using su.. but I didn't manage. Can someone give me a help?
