Oh?  Considering that in the standard pg_get_functiondef output, the
ending $function$ delimiter is always on the very last line, that sounds
pretty useless.  +1 for just numbering forward from the start line.

BTW, the last I looked, \sf+ was using what I thought to be a quite ugly
and poorly-considered formatting for the line number.  I would suggest
eight blanks for a header line and "%-7d " as the prefix format for a
numbered line.  The reason for making sure the prefix is 8 columns rather
than some other width is to not mess up tab-based formatting of the
function body.  I would also prefer a lot more visual separation between
the line number and the code than "%4d " will offer; and as for the
stars, they're just useless and distracting.
