Struct TriggerDef 

pub struct TriggerDef {
    pub name: String,
    pub table: String,
    pub timing: String,
    pub events: Vec<String>,
    pub for_each: String,
    pub function: String,
    pub update_columns: Vec<String>,
    pub enabled: bool,
    pub when_condition: String,
}

v7.12.4 — catalogued trigger. References its function by name; the function must exist at TRIGGER creation time (forward references are deferred to v7.12.5+).

Fields

name: String

table: String

Watched table. Trigger is dropped when the table drops.

timing: String

"BEFORE" / "AFTER" / "INSTEAD OF". Stored as the uppercased keyword so deserialised catalogs round-trip without canonicalisation surprises.

events: Vec<String>

Each entry is one of "INSERT" / "UPDATE" / "DELETE" / "TRUNCATE". INSERT OR UPDATE parses to two entries.

for_each: String

"ROW" / "STATEMENT". v7.12.4 ships "ROW" only; "STATEMENT" parses and persists but the executor refuses it at trigger fire time.

function: String

Name of the PL/pgSQL function to invoke.

update_columns: Vec<String>

v7.13.0 — UPDATE OF col, col, … column-list filter (mailrs round-5 G7). Non-empty means the trigger fires only when at least one of these columns appears in the UPDATE’s SET list. Empty = no column filter. Stored in catalog FILE_VERSION 23+; older catalogs deserialise with an empty vec.

enabled: bool

v7.16.1 — whether the trigger fires when its watched event occurs. Toggled by ALTER TABLE … { ENABLE | DISABLE } TRIGGER …; pg_dump –disable-triggers wraps every data block with a DISABLE/ENABLE pair so the rows already-computed in prod don’t get re-rewritten. Defaults to true at CREATE TRIGGER time. Stored in catalog FILE_VERSION 25+; older catalogs deserialise with enabled = true.

when_condition: String

v7.39 (round 138) — the deparsed WHEN ( condition ) predicate text (re-parsed at fire time to filter row triggers). Empty = no WHEN. Persisted from FILE_VERSION 70; older catalogs read back empty.
