Below are the configuration parameters PGPOOL SET can change its value
in the session. Do you have any concern here?

		{"log_statement", CFGCXT_SESSION, LOGGING_CONFIG,
		{"log_per_node_statement", CFGCXT_SESSION, LOGGING_CONFIG,
		{"log_client_messages", CFGCXT_SESSION, LOGGING_CONFIG,
		{"check_unlogged_table", CFGCXT_SESSION, GENERAL_CONFIG,
		{"allow_sql_comments", CFGCXT_SESSION, LOAD_BALANCE_CONFIG,
		{"client_idle_limit", CFGCXT_SESSION, CONNECTION_POOL_CONFIG,
		{"client_idle_limit_in_recovery", CFGCXT_SESSION, RECOVERY_CONFIG,
		{"log_error_verbosity", CFGCXT_SESSION, LOGGING_CONFIG,
