Hi,<br><br>I have recently tried installing postgesql 8.4 with PostGIS 1.5 ( now clean installs with v 1.4 instead ) onto to separate machines using the windows installer. I have only now realised that the buffer function is not available, despite being in the functions list. I checked the postgis_version() and the result was "1.4 USE_GEOS=1 USE_PROJ=1 USE_STATS=1".<br><br>The last time I installed this at work the correct geos module etc were installed. I have looked around and I can't find anything to say how I can manually change this. I believe it should be looking at the corrrect library as I found in the bin folder the libgeos-3-2-0.dll, libgeos_c-1.dll, libproj.dll files, but I don't know anything about them or how they are being referenced, other thatn one says 3.2 on it. I have tried looking for a postgis_config file, but I don't think that is something available to windows users(?)<br><br>Sorry for being so clueless, but I am worried as I have a deadline on friday and need to be able to use this functionality!<br><br>many thanks,<br>Rebecca<br> </body>
