~pooled_connection();
If this->valid() == true
,
returns the owned connection to the pool and marks it as pending reset.
If your connection doesn't need to be reset (e.g. because you didn't mutate
session state), use return_without_reset
.
May cause a mutation on the connection pool that this
points to. Thread-safe for a shared pool only if it was constructed with
pool_params::thread_safe
set to true.
