<P><FONT SIZE=2>Well actually I should elaborate. If you are building your own aggregate functions or doing something like<BR>
<BR>
SELECT ST_Unite_garray(ARRAY(SELECT the_geom FROM foo))<BR>
FROM foo2<BR>
<BR>
Is often times much more efficient than using ST_Union. Aside from you can't easily use ST_Union with something like the above.<BR>

hmm I use those functions in some code I have. So that would be kind of breaking in a major way for me.<BR>
<BR>
Besides there is no counterpart to those particular functions in an obvious sense like _ST_Intersects<BR>
so some of those functions I consider a bit fuzzy as to whether they should be considered private except they are not documented.<BR>

Unfortunately, when we function re-named things for 1.2, things got a <BR>
little out-of-hand, and every single function ended up with an ST_* <BR>
sibling. I'd like to back away from that a bit now, and flip private <BR>
functions into _ST_* space. Some examples are st_geom_accum, <BR>
st_unite_garray, etc. I'd like to do it without leaving the old <BR>
variants around. This is "breaking", but since the functions are <BR>
private, hopefully not actually breaking.<BR>
