[postgis-users] MULTIPOINT WKT - parentheses or no parentheses?

[Paragon Corporation]

FWIW:  SQL Server accepts both formats too:
 
SELECT Geometry::STGeomFromText('MULTIPOINT(1 2,3 4)',0)

 

But it outputs the separated:

SELECT Geometry::STGeomFromText('MULTIPOINT(1 2,3 4)',0).STAsText();

MULTIPOINT ((1 2), (3 4))

As far as i know, postgis accepts both formats as inputs. Specifically, if
you want to represent a multipoint in syntax WKT, you will use comma to
delimitate the values (e.g. "MULTIPOINT ( -1 1, 0 2, 3 4)" ). However,
postgis use an alternate and acceptable WKT representation for multipoint
using parenthesis to seperate each point (e.g "MULTIPOINT ((-1 1), (0 2), (3
4))" ), but will output the non-parenthetical version in the ST_AsText,
ST_AsEWKT output.
Now, i don't know if any application support both formats...
