max_connectionsaffects how the PostgreSQL server and client connections behave. You can use this to configure the maximum number of parallel connections that a PostgreSQL server can support. The formula used to calculate this is: max_connections = max(4 * number of CPU cores, 100) This makes ...
but it also increases the load on the database server.pg_dumpopens the number of jobs + 1 connections to the database, so make sure themax_connectionssetting is high enough to accommodate all connections. The number of jobs should be equal to or less than the number of vCPUs...
Often, you only need to fine tune autovacuuming, max_connections and effective_cache_size. To change settings, use database parameter groups and then restart the database instance. Amazon Aurora: Defaults vary by instance size. Often, you only need to fine tune autovacuuming, max_connections ...
postgres=> show max_connections; In Aurora, the default parameter group contains database engine defaults and Amazon RDS system defaults based on the engine, compute class, and allocated storage of the instance. You c...

ssl_max_protocol_version 此参数指定允许连接的最大 SSL/TLS 协议版本。 有效值为 TLSv1、TLSv1.1、TLSv1.2 和 TLSv1.3。 支持的协议取决于所使用的 OpenSSL 版本,旧版本不支持最现代的协议版本。 如果未设置,则忽略此参数,连接将使用后端定义的最大界限(如果设置)。 设置最大协议版本主要用于测试或某些组件...
如果设置为 0,压缩将被禁用。 默认值为 0。如果建立没有 SSL 的连接,则忽略此参数。If set to 1, data sent over SSL connections will be compressed. If set to 0, compression will be disabled. The default is 0. This parameter is ignored if a connection without SSL is made. ...
