pub enum UpdateOldKind {
None,
Key,
Full,
}Expand description
What kind of “old tuple” precedes the UPDATE’s NEW tuple (if any).
Variants§
None
No old tuple in the message (replica identity DEFAULT, key unchanged).
Key
‘K’ — only the replica-identity-key columns are in the old tuple.
Full
‘O’ — the full old tuple (REPLICA IDENTITY FULL).
