Hi We can see from below similar queries are frequently reported as Slowest individual queries. During the same time period high Read IOPS .Please let me know what is the cause for this fetch statements. Let me know as well regards this more information.
FETCH 100 FROM c2; FETCH 100 FROM c6; FETCH 100 FROM c2;
Someone has declared a cursor, and is fetching from it. When I see these types of queries, they are usually coming from postgres_fdw.
It is annoying that it shows you the FETCH statement itself, and not the original statement. If you can use auto_explain, which will show you the original statement.
