A few very minor comments while quickly paging through:

1. non-ASCII tests are going to cause problems in one platform or
another.  Please don't include that one.

2. error messages
   a) please use ereport() not elog()
   b) conform to style guidelines: errmsg() start with lowercase, others
      are complete phrases (start with uppercase, end with period)
   c) replace
      "The type you was trying to transform can't be represented in JSONB"
      maybe with
      errmsg("could not transform to type \"%s\"", "jsonb"),
      errdetail("The type you are trying to transform can't be represented in JSON")
   d) same errmsg() for the other error; figure out suitable errdetail.

3. whitespace: don't add newlines to while, DirectFunctionCallN, pnstrdup.

4. the "relocatability" test seems pointless to me.

5. "#undef _" looks bogus.  Don't do it.
