Have you considered a ST_Transform into a geometry type nested within the ST_Union or ST_Collect? PostGIS docs (from amercader's link) say they use that function internally for some geography operations.

If no band is specified for unioning, band num 1 is assumed. The resulting raster's extent is the extent of the whole set. A single-input variant of ST_Union. The input may be a single geometry, a MultiGeometry, or a GeometryCollection. The union is applied to the individual components of the input. This allow using this function to fix MultiPolygons which are invalid due to overlapping components. St_Union comes in two flavors, aggregate and simple.
