Tom Lane 717e8a1e52 Avoid double transformation of json_array()'s subquery. 
transformJsonArrayQueryConstructor() applied transformStmt() to
the same subquery tree twice.  While this causes no issue in many
cases, there are some where it causes a coredump, thanks to the
parser's habit of scribbling on its input.

Fix by making a copy before the first transformation (compare
0f43083d1).  This is quite brute-force, but then so is the
whole business of transforming the input twice.  Per discussion
in the bug thread, this implementation of json_array() parsing
should be replaced completely.  But that will take some work
and will surely not be back-patchable, so for the moment let's
take the easy way out.

Oversight in 7081ac46a.  Back-patch to v16 where that came in.
