Comment(by strk):

 Some GEOS features are off when you build PostGIS against an older GEOS.
 After you upgrade GEOS you see the _new_ version reported by
 postgis_full_version() and can wonder "why don't I have this
 functionality?"

 I've added the build-time version of GEOS into the error message that
 comes out when you try to access the unavailable functionality, but it's
 still confusing.

 Example (made out):

 {{{
  $ SELECT ST_SharedPaths(x,y) FROM mytable;
  ERROR: you need GEOS 3.3.0+ for this to work
  $ SELECT postgis_full_version();
  ... GEOS 3.3.8 ...
 }}}
