Struct CreateTriggerStatement 

pub struct CreateTriggerStatement {
    pub name: String,
    pub or_replace: bool,
    pub timing: TriggerTiming,
    pub events: Vec<TriggerEvent>,
    pub table: String,
    pub for_each: TriggerForEach,
    pub function: String,
    pub update_columns: Vec<String>,
    pub when_condition: Option<Expr>,
}

v7.12.4 — CREATE [OR REPLACE] TRIGGER. Always row-level (FOR EACH ROW) in v7.12.4 — statement-level triggers parse but the executor refuses them. WHEN (cond) clauses are out of scope; the trigger function can short-circuit on a leading IF inside its body once v7.12.5 lands IF.

Fields

name: String

or_replace: bool

timing: TriggerTiming

events: Vec<TriggerEvent>

At least one event; INSERT OR UPDATE OR DELETE parses to three entries in order.

table: String

for_each: TriggerForEach

FOR EACH ROW vs FOR EACH STATEMENT. v7.12.4 ships only Row; Statement parses but the executor refuses.

function: String

Name of the function to invoke. The function must exist at CREATE TRIGGER time — PG18-measured (round 753): PG refuses a forward reference (function no_such_fn() does not exist), so requiring it IS the PG behaviour (the old note claimed the opposite).

update_columns: Vec<String>

v7.13.0 — UPDATE OF col, col, … column-list filter (mailrs round-5 G7). Non-empty only when the events list contains UPDATE and the user wrote the column-list filter. PG fires the trigger only when at least one of these columns appears in the SET clause; SPG conservatively fires on any UPDATE matching the listed columns or rewriting them at the row level. Empty vec = no filter (fire on every UPDATE).

when_condition: Option<Expr>

v7.39 (round 138) — WHEN ( condition ) row-level filter: the row trigger fires only when the condition (over NEW / OLD) is true. None = no WHEN (fire unconditionally). Not allowed on INSTEAD OF triggers.
