As as matter of fact, this one points to something that seems to be
real.  Most of the blobs had better be trimmed down.

Looking at the code paths in this module, it looks like this could be
even simpler than what Jacob is shaving, checking for:
- Objects start and end, including booleans, ints and strings for the
quotations.
- Nested objects, including arrays made of simple JSON objects.

Some escape patterns are already checked, but most of them are
missing:
https://coverage.postgresql.org/src/test/modules/test_json_parser/test_json_parser_incremental.c.gcov.html

There is no direct check on test_json_parser_perf.c, either, only a
custom rule in the Makefile without specifying something for meson.
So it looks like you could do short execution check in a TAP test, at
least.
