And here they are.

I realized that the patch for the "other sql/json functions" part is
relatively straightforward and has no dependence on the "sql/json
query functions" part getting done first.  So I've made that one the
0001 patch.  The patch I posted in the last email is now 0002, though
it only has changes related to changing the order of the patch, so I
decided not to change the patch version marker (v1).
