The time to wait (in seconds) while trying to execute a command before terminating the attempt and generating an error. The time to wait (in seconds) while trying to establish a connection before terminating the attempt and generating an error. This is useful in clustered configurations to force load balancing between a running server and a server just brought online. Connections which have exceeded this value will be destroyed instead of returned from the pool. The total maximum lifetime of connections (in seconds). How many seconds the pool waits before attempting to prune idle connections that are beyond idle lifetime (see Connection Idle Lifetime). The time (in seconds) to wait before closing idle connections in the pool if the count of all connections exceeds Minimum Pool Size. Whether connection pooling should be used. When enabled, parameter values are logged when commands are executed. When enabled, PostgreSQL error and notice details are included on PostgresException.Detail and PostgresNotice.Detail.
