I'm really sorry for confusing people, but I've one more revision.
This is my first time attempting to commit such a large patch.
Major changes are following:
* We find it ridiculous to save ErrorData for possible latter throw.
Now, we either throw an error immediately or return jperError. That
also allows to get rid of unwanted changes in elog.c/elog.h.
* I decided to change behavior of jsonb_path_match() to throw as less
errors as possible. The reason is that it's used to implement
potentially (patch is pending) indexable operator. Index scan is not
always capable to throw as many errors and sequential scan. So, it's
better to not introduce extra possible index scan and sequential scan
results divergence.
So, this is version I'm going to commit unless Nikita has corrections
or anybody else objects.
