How about a format like this then:

# Comment
Section: Class 2F - SQL Routine Exception
macro_name sqlstate plpgsqlname is_error

That is: # and blank lines are comments, lines starting with "Section:"
are section names (needed for SGML output), the rest are whitespace
separated strings. is_error is 0 or 1, if it's 0 we don't generate a
plpgsql condition for it.

If we go for that format, we'll end up with one new plpgsql error
(nonstantard_use_of_escape_character) that was omitted from previous
releases.
