[postgis-users] Merge rectangles

In the table portal.catalog
column poly is a geometry (always a rectangle, with datum EPSG 4326)
column type is a text field.
I want to find all the records who have a type of "CADRG" and merge the
polygons into the simplest shape that covers all the items in the array
(I.e. if they form a square with a hole, then I want that, if it has to be a
multipolygon, so be it).
Is this the correct way to do that?
