Pool mode configuration

Fields

mode: PoolingMode

Default pooling mode

max_pool_size: u32

Maximum connections per node

min_idle: u32

Minimum idle connections

idle_timeout_secs: u64

Idle timeout (seconds)

max_lifetime_secs: u64

Max connection lifetime (seconds)

acquire_timeout_secs: u64

Acquire timeout (seconds)

reset_query: String

Reset query to run when returning connection to pool

prepared_statement_mode: PreparedStatementMode

Prepared statement mode

skip_clean_reset: bool

Conditional reset (Transaction/Statement pooling): when true, a connection that provably touched no session state (no SET/GUC, temp table, prepared statement, LISTEN, advisory lock, …) is parked WITHOUT running reset_query, saving a backend round-trip per clean transaction. Classification is conservative — anything not provably session-neutral still runs the full reset — so a misclassification only ever costs an unnecessary reset, never leaks state. Off by default; intended for autocommit / simple-protocol workloads. See the stmt_leaves_session_state classifier for the exact (documented) limitation around session-setting user functions.
