In the old protocol there used to be support for more then one error
arriving, in which case they were concatenated. What is happening with
that?

Shouldn't the position be available as a separate field, so client
programs can do their own highlighting or whatnot?

One more thing: It has always annoyed me that PQerrorMessage() returns the
text with a trailing newline. Since we now redefined newlines to be
paragraph breaks, should this be changed (in a backward-compatible
fashion)?
