"PostgreSQL 在 ${CURRENT_CONNECTION_LIMIT} 个并发连接下无法扩展,消耗 ${CURRENT_MEMORY_OVERHEAD_TOTAL} MB。请考虑调整你的 max_connections 和 work_mem 参数。"fi# 根据可用内存和当前工作内存计算建议的最大连接数 SUGGESTED_MAX_CONNECTION=$
Nowwork_memhas a direct influence on query performance:sorting will be fasterif it can use enough RAM, or PostgreSQL may prefer a fasterhash joinorhash aggregateand avoid a sort at all. So settingmax_connectionshigh will make queries perform slower than they could, unless you want to risk ...

When you tunemax_connectionsin Amazon RDS for PostgreSQL or Amazon Aurora PostgreSQL-Compatible, consider the available instance types and their allocated resources, and focus on memory and CPU capacity. Storage and I/O details are managed by AWS, so you can monitor general workload characteristics...
Postgres is not good in handling lots of connections, that's why lots of postgresql connection poolers exist and they are getting used in production. Also we're handling about 800 rps without having to tweak postgresql connections, that's why I don't think your "high load" suffices the ...
In this blog, we listed AWS RDS Max Connections Limit as per DB Instance Type. Too many DB connections error because of the max DB connection limit exceeded.
