Signature of ST_Union would look like… 

ST_Union(raster, ARRAY[]::record[])

Where ARRAY[]::record[] is… 

ARRAY[ROW(nband, uniontype), ... ]

Example… 

ST_Union(raster, ARRAY[ROW(1, 'LAST'), ROW(2, 'FIRST'), ROW(3, 'MEAN')])

We could use a composite type but types are pains to manage in the long term…
