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))

Subject: Re: [postgis-users] MULTIPOINT WKT - parentheses or no parentheses?
Mike
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...
