 This may not be a bug, but I figured you may be getting bored :)

  does OGC have a concept of TIN, TRIANGLE,  empties?
 {{{
 SELECT  ST_COLLECT(ST_GeomFromText('POLYGON
 EMPTY',4326),ST_GeomFromText('TRIANGLE EMPTY',4326)) ;
 }}}


 gives error:


 {{{
 ERROR:  getPoint_internal called outside of ptarray range (n=0,
 pa.npoints=0, pa.maxpoints=0)
 }}}

 I'll check some others.

 Should this be legal? All TIN TRIANGLE Give invalid OGC WKT (too short)


 {{{
 SELECT  ST_COLLECT(ST_GeomFromText('TIN EMPTY',4326),ST_GeomFromText('TIN
 EMPTY',4326)) ;

 SELECT  ST_GeomFromText('TIN EMPTY',4326) ;
 }}}

 That yields a:

 OGC WKT (too short)
