Subject: pgsql: Add special case fast-paths for strict functions

Message-ID: <[email protected]> (raw)

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.
