[postgis-devel] sfcgal && extensions

[Paragon Corporation]

Yes,  It can't be part of postgis extension anyway.  It has to be a separate
extension like point cloud. Otherwise we'd have to force everyone to start
building with SFCGAL since it adds additional functions not supported
natively by PostGIS or GEOS and we can't have two different postgis
extensions of same version with disparate number of functions.
 
Internally, and Olivier can correct me if I am wrong.  I think SFCGAL
surplants some functions because of the flipping of back ends when compiled
with SFCGAL so for the functions where SFCGAL overlaps with main PostGIS,
SFCGAL overrides the GEOS behavior even when sfcgal.sql is not installed.
That part is very hazy to me though.
 
Thanks,
Regina

That sounds right.

It looks to me like sfcgal.sql never gets added to the postgis extension,
even when it's been built and enabled... so there's no way to use the cgal
functions in an extension context, only if you manually load the sfcgal.sql
file yourself. Correct interpretation?
