I spent awhile hacking on this, and made a lot of things better, but
I'm still very unhappy about the state of the comments. You changed
the APIs of a bunch of functions, often into fairly subtle things,
and you did not touch even one of their API-specification comments.
As an example, next_token() now needs something like
"On error, log a message at ereport level elevel and set *err_msg to
an error string. Note that the return value might be either true or
false after an error; *err_msg must be checked to determine that.
Hence, *err_msg had better be NULL on entry, or you won't be able
to tell."
Having to write such a thing might even convince you that you should
try a little harder to make the behavior less confusing. Just adding
arguments, and not changing the result-value specification, is not
necessarily the best way to do this.
I haven't looked at the docs yet.
I'm still not very happy about the choice of view name ...
