Operators Mathematical operators are provided for many PostgreSQL types. For types without common math- ematical conventions for all possible permutations (e.g., date/time types) we describe the actual date handling on newer glibc libraries (Tom) • Fix PowerPC SMP locking (Tom) • Prevent gcc -ffast-math from being used (Peter, Tom) • Bison > = 1.50 now required for developer builds • Kerberos 5 support (Thomas) Rename functions to round(), sqrt(), cbrt(), pow() for float8 (Thomas) Add transcendental math functions (e.g. sin(), acos()) for float8 (Thomas) Add exp() and ln() for NUMERIC type Rename NUMERIC
