libecpg_compat.so is for Informix compatibility. It contains the Informix-specific calls. > Is there some way of building with Pg v8.0 ECPG lib and running on a > system with Pg v8.4 ECPG lib? or vice versa? and is libecpg_compat > intended for that purpose? You can build the src/interfaces/libpq and src/interfaces/ecpg/ecpglib directories in the old version and install them side by side with the new version. The 8.4 server works happily with the old ECPG client. Best regards, Zoltán Böszörményi -- Bible has answers for everything.
