I perused this version in comparison to the last version I reviewed, finding
minor problems.  First, a warning:

tablecmds.c: In function `ATExecAddConstraint':
tablecmds.c:5898: warning: `fk_element_type' may be used uninitialized in this function
tablecmds.c:5898: note: `fk_element_type' was declared here

I don't see an actual bug; add a dead store to silence the compiler.

Keep that json test.

Project style is not to break message literals; instead, let the line run
long.  There are a few more examples of this in your patch.


Those problems are isolated and do not impugn design, so committer time would
be just as well-spent on the latest version.  As such, I'm marking the patch
Ready for Committer.  Thanks to Rafal Pietrak for his helpful review.
