PostGIS Layer Failing

[William Kyngesburye]

Which version of PostGIS are you using?  There is a bug in PostGIS  
1.3.1 and SVN that was fixed a few days ago that affects Leopard.   
PostGIS had a function with a commonly used name, and this function  
was added to the Leopard libSystem.  This gets used in PostGIS instead  
of its own, causing Postgres to crash.

Either install PostGIS from the latest SVN, or install my latest  
PostGIS if you are using my binaries.


If that's not the problem, try looking in the console and system logs,  
as well as the Apache logs.  A library problem may just appear as an  
unidentified error at the PHP level, and digging into system logs may  
be needed to identify the problem.
