it's not like this. Try as a not owner user to use \d to retrieve
information and you'll get all you need to reflect. When I opened ticket '71
I also suggested a whay to get Primary keys and foreign keys w/o any
privileges, just studying what psql does upon '\d table_name' with option -E.

security by obscurity? mmh not what I call security!
A broken reflection is what make me for the moment have all people
connect with the same user. That's *totally* unsecure!
And to spend one more word about reflection: I definitely want a single
point where info on the db are stored, and that's the db. I may even forget
about how many application I made to get to a db but if the structure is
reflected all the times I'm sure the information get to the wright place when
needed. (Btw: I'd really like to see the error raised when autoloading if
the table does not exist, as recently proposed)
