I think the issue is portability.

I wonder what readline is doing there. Readline is for PSQL command completion and history. As for the rest, they are *optional* modules that apparently your RPM builder chose to include; I build from source and my only dependencies are bison, flex, gcc and perl. > It would appear that linking against libraries is just fine, I don't > see that uuid is any different. Is it portable to all platforms we support? How does it generate its machine identifier? One of the differences between an add-in and core code is support for all PostgreSQL platforms. -- Josh Berkus Aglio Database Solutions San Francisco ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
