Comment(by robe):

 Olivier,

 Sorry I should have looked closely at the patch.  I see 2 main issues

 1) Your SQL functions can't be folded into postgis.sql, they have to be in
 a separate file similar to what is done for topology and tiger geocoder.
 This is for 2 reasons mostly because of the way extensions work

 a) functions in an extension can't be different based on whether or not
 you compile with something.

 b) sfcgal function are in a separate schema and all functions in an
 extension NEED TO BE in same schema.

 c) You need to be able to install sfcgal as an extension for it to make
 the 9.1+ cut. If you need help with this, I can help out.  That means you
 will need a folder in /extensions folder similar to what is done with
 postgis, postgis_topology, postgis_tiger_geocoder

 That said please make these changes before committing (might be better for
 you to just attach another patch and I'll inspect to see if I see any
 glaring issues).  If you can't we really need to push this to 2.2.
