System Configuration

Architecture (example: Intel Pentium) : Intel Pentium

Operating System (example: Linux 2.0.26 ELF) : Linux 2.2.16-4 (Redhat)

Please enter a FULL description of your problem:
------------------------------------------------

That documentation on access to tables seems to be at odds with what happens.
How grant affects access isn't very intuitive. I am not sure if the handling
of access to tables or the documentation is broken.

The problem is that when access is granted explicitly, the implicit access
by the owner of the object (at least for select) is lost. The work around
is to also give explicit access to the owner.

Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:
