Sorry, I do have a pg_shadow file, but it's empty. 

I have a pg_pwd too with this text inside : 
[postgres@bxsgalena data]$ cat pg_pwd
postgres        0       x       x       x       x       1       \N

What is it used for? I couldn't find info about this file in html docs. I have another 
postgre installed here and in that machine (working very well) pg_pwd is empty.

Regards.
