Hi Paul,

thanks for your reply. I checked what you mentioned and I found that 
liblwgeom.so is well placed and "refreshed" when I do make install.

But you gave me an idea about libraries. I had an ancien postgresql 
installation and the database I use now was created with this ancien 
postgresql. So I renamed the old folder then I tried to *"select 

ERROR:  could not access file 
"/data/ulysse/postgresql_8.2.4/lib/liblwgeom.so.1.2": No such file or 
STATEMENT:  select postgis_version();

This indicate the old path! Can I change this? Or I have to start 
another database folder?

I couldn't not see this path anywhere in my configuration files.
