Description
It could be me being unable to read it, but isn't the TIN example in the manual page invalid:
http://postgis.refractions.net/docs/using_postgis_dbmanagement.html#EWKB_EWKT
It contains this:
TIN( ((0 0 0, 0 0 1, 0 1 0, 0 0 0)), ((0 0 0, 0 1 0, 1 1 0, 0 0 0)) )
Which is a 'TIN Z' where the first triangle is not a triangle (first segment is a point)

Olivier: your interpretation of this ? Is a vertical line in a triangle valid ?

TRIANGLE((0 0 0, 0 0 1, 0 1 0, 0 0 0)) is not valid in 2D (no area) but perfectly valid in 3D.

So I am considering this a non-issue.

See TracTickets

Olivier: do you confirm the example is an invalid TIN ?
