false)?This way people who don't want/need the extra overhead don't have to deal with it, and those who want to use
postgresfor scientific/engineering/animation/etc apps (where 2D doesn't quite cut the mustard) can have it available to
them.I was thinking that it would allow a whole new set of applications to take advantage of the fact that postgres
providesnative geometric types. After all, you can use just about any db engine to handle geometric data with
traditionalsql and stored procedures. The point of the builtins is so you have a standard set of algorithms, and that
youdon't have to constantly reinvent the wheel. Like I said in my earlier message, I can patch the source for myself,
andgo about my merry way. The geometry portions really don't seem to change very frequently (the differences between
8.0.3,and 8.1beta were minimal), and except for the line stuff, the changes were trivial, so personal maintenance
shouldn'tbe a problem. I just thought I'd share my work.:-)<br /><br /><blockquote type="CITE"><pre>
