A PostgreSQL connection string, also known as a connection URL, is a format used to specify connection parameters to connect to a PostgreSQL database. The URL provides details like the host, port, database name, user, and password. This format is widely used in applications for easily configu...
Several libpq functions parse a user-specified string to obtain connection parameters. There are two accepted formats for these strings: plain keyword/value strings and URIs. URIs generally follow RFC 3986, except that multi-host connection strings are allowed as further described below. Keyword/Value...

FATAL: connection limit exceeded for non-superusers 原因:非超级用户的连接数(max_connections - superuser_reserved_connections)超过了设定值 解决办法:增加max_connections设定值,但如果增加了过多的话,数据库负担太大还容易产生内存错误。可以记住pg-pool等工具来辅助解决。
以下功能都通过一个连接参数配置,支持的参数如下表所示。所有的新增参数的生效范围都控制为连接级别,随Connection的生命周期生效。 参数名 说明 autoCommit 开启或关闭参数形式的自动提交。取值如下: true(默认):开启参数形式的自动提交。 false:关闭参数形式的自动提交。
