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
its primary function is to store data, securely and supporting best practices, and retrieve it later, as requested by other software applications, be it those on the same computer or those running on another
max_wal_senders : Must be set to 3 if you are starting with one slave. For every slave, you may add 2 wal senders. wal_keep_segments : Set the WAL retention in pg_xlog (until PostgreSQL 9.x) and pg_wal (from PostgreSQL 10). Every WAL requires 16MB of space unless you have expl...
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 ...
If not specified, the default is TLSv1.2, which satisfies industry best practices as of this writing. 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。

The max_connections parameter specifies the maximum concurrent connections allowed in a database. If the value of this parameter is large, the RDS for PostgreSQL database may request more System V shared memory or semaphore. As a result, the requested shared memory or semaphore may exceed the ...
