Enum PoolerRefusal 

pub enum PoolerRefusal {
    Autocommit,
    SessionState,
}

Why a transaction pooler refuses a guest statement.

Variants

Autocommit

It cannot run in a transaction, so its SET and RESET would land on other server connections; such DDL belongs in deploy-time migrations.

SessionState

It sets session state, which would outlive the transaction on a server connection other clients share. set_config(…, false) and DO blocks cannot be recognised this way.
