[wktraster] DumpAsWKTPolygons uses PostgreSQL 8.4 default construct

[robe]

Just tried install wktraster on 8.3 and couldn't because of the DEFAULT used in DumpAsWKTPolygons

DumpAsWKTPolygons(raster,DEFAULT int )

This is a feature that was introduced in 8.4, so will prevent 8.3 users from installing WKT Raster.

Note the current PostGIS 2.0 currently supports 8.3, but it is very likely when we finally release we may drop support for 8.3. Since this isn't currently working yet, and has equivalent 8.3 workaround seems a bit early to be leaving 8.3 people out in the cold because of this.
