I know v45 is very different from v47.
but v45 contains all the remaining features to be implemented.

I've attached 2 files.
v45-0001-propagate-passing-clause-to-every-json_ta.based_on_v45
after_apply_jsonpathvar.sql.

the first file should be applied after v45-0001-JSON_TABLE.patch
the second file has all kinds of tests to prove that
applying JsonPathVariable to the NESTED PATH is ok.

I know that v45 is not the whole patch we are going to push for postgres17.
I just want to point out that applying the PASSING clause to the NESTED PATH
works fine with V45.

that means, I think, we can safely apply PASSING clause to NESTED PATH for
feature "PLAN DEFAULT clause", "specific PLAN clause" and "sibling
NESTED COLUMNS clauses".
