Comment(by robe):

 I'm beginning to think this is a bug in PostgreSQL rather than PostGIS.
 What is really really odd why I think that is that the ST_AsText function
 called with unknown is nothing but this:


 {{{
 CREATE OR REPLACE FUNCTION st_astext(text)
   RETURNS text AS
 ' SELECT ST_AsText($1::geometry);  '
   LANGUAGE sql IMMUTABLE STRICT
   COST 100;
 }}}


 And yet if you call:


 {{{
 SELECT ST_AsText('POINT(3 4 hi)'::geometry);
 }}}

 IF doesn't crash.  How bizarre is that? It's almost like the IMMUTABLE
 STRICT is having a weird side effect.

 pramsey -- I thought we had an issue like this where wrapping logic in a
 fucntion would craash but calling the same logic explicitly wouldn't, but
 can't recall what that ticket was.  Does that sound familiar?
