[postgis-devel] Public/Private API, ST_*/_ST_*

[Obe, Regina]

Well actually I should elaborate.  If you are building your own aggregate functions or doing something like

SELECT ST_Unite_garray(ARRAY(SELECT the_geom FROM foo))
FROM foo2

Is often times much more efficient than using ST_Union.  Aside from you can't easily use ST_Union with something like the above.

hmm I use those functions in some code I have.  So that would be kind of breaking in a major way for me.

Besides there is no counterpart to those particular functions in an obvious sense like _ST_Intersects
so some of those functions I consider a bit fuzzy as to whether they should be considered private except they are not documented.

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