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.
