That still works with respect to libpq's internally-generated errors,
which is as far as I know the only case that the concatenation was
actually useful for.

Yes, it is.  The question here is what the backwards-compatible
PQerrorMessage() call should produce.  Do you think position should
get left out of that?  My thought was that the "terse" form should
carry everything that is likely to fit on one line, and position
would usually fit on the same line with "syntax error".  Also, an app
that is using PQerrorMessage() rather than constructing its own
error message from the individual fields is likely not gonna do anything
as helpful as highlighting ...

The backwards-compatible part *is* that PQerrorMessage() returns text
with a trailing newline.  If you fetch the individual fields, they don't
have trailing newlines.
