Issue 63: ST_Max_Distance is not yet implemented?
http://code.google.com/p/postgis/issues/detail?id=63

New issue report by robe.... at cityofboston.gov:
What steps will reproduce the problem?
SELECT ST_Max_Distance(ST_GeomFromText('LINESTRING(1 0, 3 0)'),
ST_GeomFromText('LINESTRING(3 0, 5 0)'))


What is the expected output? huh I think 4

What do you see instead?

ERROR:  This function is unimplemented yet

********** Error **********

ERROR: This function is unimplemented yet
SQL state: XX000


What version of the product are you using? On what operating system?
Windows - "POSTGIS="1.3.3" GEOS="3.0.0-CAPI-1.4.1" PROJ="Rel. 4.6.0, 21 Dec
2007" USE_STATS"
I think I tried on OpenSUSE 11 1.3.4 SVN and got the same unsatisfying
answer.  I'll have to double-check that.


Please provide any additional information below.
I think the trunk lwpostgis.sql.in.c has this comment

Maximum distance between linestrings. 2d only. Very bogus.
-- Availability: 1.2.2

And I thought it did something way back yander, but could have been my
imagination or it was removed because as the comment says its bogus?
