That means that it operates on rows of data, in the same way the SUM() and AVG() functions do and like most aggregates, it also ignores NULL geometries. Availability: 2.1.0 ST_Union(rast, unionarg) variant was introduced. Enhanced: 2.1.0 ST_Union(rast) (variant 1) unions all bands of all input rasters. Prior versions of PostGIS assumed the first band. Enhanced: 2.1.0 ST_Union(rast, uniontype) (variant 4) unions all bands of all input rasters.

You are getting multiple (multipolygons) because each row represents those that actually form an intersecting union. ST_Collect simply concatenates unions, but if you perform this after ST_Union, you should get what you want, which will be one giant multipolygon. create table corine00 as select st_union(the_geom) as the_geom, sum(area_ha) as area_ha, substr(code_00,1,2) as code_00 from clc00_c31_forests group by substr(code_00,1,2) Note: All forest codes start with '31' and I'm using PostGIS 1.4, GEOS version: 3.2.0-CAPI-1.6.0 PostgreSQL UNION examples. Let’s take some examples of using the PostgreSQL UNION operator. 1) Simple PostgreSQL UNION example. The following statement uses the UNION operator to combine data from both tables: ST_Union geometrically merges geometries where they overlap, and splits linestrings at intersections.
ST_Union geometrically merges geometries where they overlap, and splits linestrings at intersections. It may return single geometries when it dissolves boundaries. Availability: 1.4.0 - ST_Collect(geomarray) was introduced.

Enhanced: 2.1.0 ST_Union(rast) (variant 1) unions all bands of all input rasters. Prior versions of PostGIS assumed the first band. Enhanced: 2.1.0 ST_Union(rast, uniontype) (variant 4) unions all bands of all input rasters. ST_Union — Returns the union of a set of raster tiles into a single raster composed of 1 band. 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.

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. ST_Union() in PostGIS and the Union tool in QGIS do different things, despite the similar names. ST_Union() is similar to the Dissolve tool in QGIS, in that it will eliminate boundaries of adjacent features and/or group single features with the same attribute values into Multi* features.
ST_Union geometrically merges geometries where they overlap, and splits linestrings at intersections. It may return single geometries when it dissolves boundaries. PostGIS ST_Collect vs.
