Thread: pgsql: Add special case fast-paths for strict functions
Add special case fast-paths for strict functions Many STRICT function calls will have one or two arguments, in which case we can speed up checking for NULL input by avoiding setting up a loop over the arguments. This adds EEOP_FUNCEXPR_STRICT_1 and the corresponding EEOP_FUNCEXPR_STRICT_2 for functions with one and two arguments respectively.
