Enum postgres_parser::sys::VariableSetKind

#[repr(u32)]pub enum VariableSetKind {
    VAR_SET_VALUE,
    VAR_SET_DEFAULT,
    VAR_SET_CURRENT,
    VAR_SET_MULTI,
    VAR_RESET,
    VAR_RESET_ALL,
}

SET Statement (includes RESET)

"SET var TO DEFAULT" and "RESET var" are semantically equivalent, but we preserve the distinction in VariableSetKind for CreateCommandTag().

Variants

VAR_SET_VALUE

VAR_SET_DEFAULT

SET var = value

VAR_SET_CURRENT

SET var TO DEFAULT

VAR_SET_MULTI

SET var FROM CURRENT

VAR_RESET

special case for SET TRANSACTION ...

VAR_RESET_ALL

RESET var
