I can see that this has been applied as of 42fa4b660143 with some
extra commits.

Anyway, I have noticed another thing in the surroundings that's
annoying.  003 has this logic:
use File::Temp qw(tempfile);
[...]
my ($fh, $fname) = tempfile();

print $fh $stdout,"\n";

close($fh);

This creates a temporary file in /tmp/ that remains around, slowing
bloating the temporary file space on a node while leaving around some
data.  Why using File::Temp::tempfile here?  Couldn't you just use a
file in a PostgreSQL::Test::Utils::tempdir() that would be cleaned up
once the test finishes?

Per [1], escape_json() has no coverage outside its default path.  Is
that intended?

Documenting all these test files with a few comments would be welcome,
as well, with some copyright notices...

        json_file = fopen(testfile, "r");
        fstat(fileno(json_file), &statbuf);
        bytes_left = statbuf.st_size;

No checks on failure of fstat() here?

        json_file = fopen(argv[2], "r");

Second one in test_json_parser_perf.c, with more stuff for fread().
