<DIV><FONT size=2>Hi.<BR><FONT size=3> </FONT></FONT></DIV>
<DIV><FONT size=2><FONT size=3> In the Online Manual of PostGIS 0.6,
length2d function still exists in<BR>"Other Functions" section, no description
about length function in<BR>"Chapter 5." But postgis.sql of PostGIS 0.6 doesn't
define<BR>length2d(returned value type Float4), length is defined(returned
value<BR>type Float8).<BR><BR> Which function does PostGIS really support?
And length function is<BR>similar to length funcion in OpenGIS Simple Features
Specification For<BR>SQL. This function's description should be in Chapter 5's
"OpenGIS<BR>Functions" section?<BR><BR> Thanks.</FONT></FONT></DIV>
