在PostgreSQL 服务器上设置 TCP keepalive 参数 PostgreSQL 服务器总是设置SO_KEEPALIVETCP 套接字来检测断开的连接,但默认的两小时空闲超时非常长。 您可以设置配置参数tcp_keepalives_idle、tcp_keepalives_interval和tcp_keepalives_count(Windows 上不支持最后一 项)来

Azure Cosmos DB for PostgreSQL 可以使用 postgresql-hll 扩展计算 count(distinct) 近似值。 在计算 count(distinct) 时,此配置条目将设置所需的错误率。 指定 0.0(默认值)会禁用 count(distinct) 的近似值;指定 1.0 不能保证结果的准确性。 建议将此参数设置为 0.005 以获得最佳结果。 此值可在运行时设置,并...
