Oops, sorry...didn't see that. Have you tried the select statement without the astext(multi()) part? I'm just going off of what I see in other PostGIS dissolve examples.

| Aug 21, 2012 at 20:07 | comment | added | dmahr | This process is known as a "dissolve". I'm not experienced with PostGIS, but I believe you can use the ST_Union command do perform the dissolve. | |
