The rule system is a key feature of PostgreSQL. It should not be deprecated,
if it doesn't work, it should be fixed.

Re: [HACKERS] Reference Guide
Hi all,

I'm writing Reference Manual pages and I have some questions about...

create rule:

      The man page says ...

           "The current rule system implementation is very brittle and
            is unstable.  Users are discouraged from  using  rules  at
            this time."

      My question are: 
            Is this command a PostgreSQL deprecated feature ?
            Sould I skip it ?
            Does it works ? 

declare:

         DECLARE cursor [ BINARY ] 
              FOR SELECT expression

      The man page says ...

           "BINARY cursors give you back the data in the native binary
            representation. Thus, binary cursors will tend to be a
            little faster since there's less overhead of conversion."
      
      My question is: 
            I can't see any difference between BINARY and normal cursors.
            Does it works ? 

                                                            Thanks, Jose'

It does work, but has some limitations in using rules for
UPDATE/DELETE/INSERT.  We need to prevent the ones that are problems.  I
am removing the warning from the manual page.
