Re: [proposal] Add an option for returning SQLSTATE in psql error message

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           not tested
Documentation:            tested, passed

This is a handy feature, and the implementation looks good to me.

There might be some nit-picking about the vertical whitespace around
the code in added to fe-protocol3.c, but I'll leave that to the committer.

The new status of this patch is: Ready for Committer
