Be wary of enforcing this timeout on connections made through connection-pooling software or other middleware, as such a layer may not react well to unexpected connection closure. Disabling validation avoids side effects of the validation process, in particular preventing false positives due to problems such as forward references.

If log_min_error_statement is set to ERROR or lower, the statement that timed out will also be logged. The intent of this feature is to allow debugging or performance-measurement libraries to be loaded into specific sessions without an explicit LOAD command being given. VACUUM might actually run but it is never allowed to clean out dead rows because a single transaction might still be allowed to see old data. The intent of this feature is to allow unprivileged users to load debugging or performance-measurement libraries into specific sessions without requiring an explicit LOAD command. If the value is 1 (the default) or above, float values are output in shortest-precise format; see Section8.1.3.
