Обсуждение: slow query
I checked all the indexes are defined on the tables however the query seems slow, below is the plan. Can any one give any pointers to verify ?

It's currently running in slightly under six milliseconds. That seems reasonably fast given the number of operations requiredto fulfill it.
In AWS RDS performance insights the client writes is high and the api which receives data on the mobile side is slow during load test.

You might try to do something about the poor selectivity estimate here:

If the planner realized that this'd produce O(100) rows not 1,
it'd likely have picked a different plan. I'm guessing that
the issue is lack of knowledge about what is_menu_item_available()
will do. Maybe you could replace that with a status column?
regards, tom lane
below is function definition of is_menu_item_available, for each item based on current day time it returns when it's available or not. The same api works fine on oracle, I am seeing this slowness after migrating the queries to postgresql RDS on AWS
