Hi EveryOne,
Please find the complete query and also explain plan. This is run on PostgreSQL 11.6 on x86_64-pc-linux-gnu. This query is being run on a logically replicated db instance for generating dynamic reports multiple times in a day. Here Task and task_history are two tables on which join is currently there based on some conditions. common_details is a json column in the task table. All indexes can be seen in the explain plan.The task table is partitioned on organisation_process_path and created_date two columns. But I could not include created_date anywhere in the query due to business requirements which the query is trying to fulfill.
Please help in highlighting any optimisations that can be done.

While those duplicative extractions sure look inefficient, it's not
clear from the (lack of) given facts whether that's the main cost,
or whether the complicated FROM clause is producing a bad plan.
I'd suggest first looking at EXPLAIN ANALYZE output to verify which
plan step(s) are slow. If it's the final output step that's expensive,
then yes the next step is to optimize the extractions.
Otherwise, see

The query is far too big. Also, there are several "parallel seq can" accesses, some of which are completely needless:
Parallel Seq Scan on task_serv_nch_q4_2020 task_1 (cost=0.00..123987.65 rows=4 width=1354) (actual time=3615.528..3615.529 rows=0 loops=1)
Rows Removed by Filter: 575139 (So, the parallel query only
returns 4 rows and discards over half a million? That would be
much better server by an index)
Parallel Seq Scan on task_serv_nch_q2_2021 task_3 (cost=0.00..110496.48 rows=52 width=1080) (actual time=2.235..5974.188 rows=20086 loops=2)
Parallel Seq Scan on task_serv_nch_q3_2021 task_4 (cost=0.00..87091.00 rows=198 width=717) (actual time=1.318..7362.202 rows=26068 loops=5)
Queries of this size usually mean that there is a problem with the data model or business analyst who doesn't understand the data model properly. Also, such queries should be sliced and diced using CTE and temporary tables.
Last, contrary to popular belief, parallel processing speeds
things up only in a very limited number of cases, usually in a
data warehouse environment. That applies to Oracle, SQL Server and
Postgres. Typical case for parallel processing is aggregating data
from one huge table. Plan like yours will include ping pong with
the messages between the parallel processes, which will take time,
especially on NUMA systems, which means on the majority of the
modern multi-processor machines. So, please rewrite the query
using CTE ("WITH" statement), some temporary tables and optimize
it piece by piece. The best strategy comes from the Roman Empire:
divide and conquer.
