[postgis-users] ST_Buffer

[Paragon Corporation]

Dave,

 

Apologies for the anti-Microsofties in our crew.  They shall be sufficiently
slapped for their behavior J.

 

Which version of GEOS are you using?  

 

Do a:

 

SELECT postgis_full_version();

 

It's possible that you are using GEOS 3.3 beta and I did run into issues but
haven't pinpointed the issues I'm having yet.  I'm not near my server that
has GEOS 3.3. to test with.

 

Thanks,

Regina

I am completely new to PostGIS and I appear to be falling at the first
hurdle. 
Trying the example in the documentation (
<http://postgis.refractions.net/documentation/manual-1.5/ST_Buffer.html>
http://postgis.refractions.net/documentation/manual-1.5/ST_Buffer.html):  
SELECT ST_Buffer(ST_GeomFromText('POINT(100 90)'), 50); 
works fine while: 
SELECT ST_Buffer(ST_GeomFromText('POINT(100 90)'), 50, 'quad_segs=4'); 
Gives a syntax error and 
SELECT ST_Buffer(ST_GeomFromText('POINT(100 90)'), 50, 4); 
crashes the server. 
What am I doing wrong? 
Versions: 
PostgreSQL 8.4.5 on Windows 7 
POstGIS 1.5.2 
Thanks Dave
