Connection exceeded alert.

Hi all,

I have been trying to find a steps or solution for past 1 year once we received a connection exceeded alert. Couldn't get any answer from anybody or internet so far.

Today I checked a pgbadger report and  matched the timeline and found that, at that time of sudden connection hike (not normal), there were 3 queries running at that time (2 update queries on table a , took 5s each, one insert query on table b which took 2.5mns).

Anybody provide me steps what all I have to do 1. At that time of connection hike 2. If I am been asked to check after sometime as connection dropped to analyse.

Please check  maximum connection / Session parameter in postgreSQL.conf file and you can increase maximum session/connection.

Please also check locking on database.

Hi Rajesh,

To effectively troubleshoot this issue, please share your current PostgreSQL configuration values for shared_buffers, work_mem, and maintenance_work_mem.

Additionally, please provide details about the application generating these queries. Are they triggered by POST or GET requests?

To gain deeper insights into query performance, execute the following commands:

EXPLAIN (ANALYZE, BUFFERS) <your_query>;

SELECT pid, usename, query, state, wait_event_type, wait_event
FROM pg_stat_activity
WHERE wait_event IS NOT NULL;
These commands will help identify performance bottlenecks and resource contention.
