Fernando,

Can you provide a reason these patches are necessary?  Are there some 
specific use cases that are trying to be addressed?

I am very reluctant to apply all of this.  The reason being, that 
without a commitment on how error codes are going to be implemented in 
the backend, I don't want to partially implement them in the jdbc 
driver.  There needs to be a consistent implementation between the jdbc 
driver and the backend (since the jdbc driver will end up passing the 
backend's codes to the client).  Depending on what the backend 
implementation is, that might even mean that the jdbc driver will 
support error codes in a non-standard way.  I am much more concerned 
with consistency between the two sets of error codes than I am with 
following the standard at the moment.  I really want to avoid needing to 
have the reinterpret all the backend error codes to conform to how these 
patches think error codes should be handled.  That will be a maintenance 
nightmare.

I think this patch goes beyond what I am comfortable applying without 
any guidance on how/when/if error codes are going to be implemented in 
the backend.

thanks,
--Barry
