I forgot you could do this...This would certainly be easier than parsing
array values returned from array_accum.  It will probably be faster as
well...but with the array approach the query would not have to be
modified each time a new department was added.  That said, a crosstab
based query could be built easily enough from a department query on the
client and then you have the best of both worlds.
