Re: [PATCH] Return command tag 'REPLACE X' for CREATE OR REPLACE statements.

Here's an updated patch that reports command status back to
ProcessUtility via 'bool' return value.

I was a bit unsure about using bool return values because it's not
immediately obvious what "true" or "false" refer to, but defining a
new enum seemed like overkill, so I went with bool anyway. Any better
ideas?

The 2nd patch also moves MOVE/FETCH command tag formatting up to
ProcessUtility, hopefully this change is for the better.
