Local execution should not change hasReturning for distributed tables (#3160) 
It looks like the logic to prevent RETURNING in reference tables to
have duplicate entries that comes from local and remote executions
leads to missing some tuples for distributed tables.

With this PR, we're ensuring to kick in the logic for reference tables
only.

Remove real time router executors (#3142) 
* Remove unused executor codes

All of the codes of real-time executor. Some functions
in router executor still remains there because there
are common functions. We'll move them to accurate places
in the follow-up commits.

* Move GUCs to transaction mngnt and remove unused struct

* Update test output

* Get rid of references of real-time executor from code

* Warn if real-time executor is picked

* Remove lots of unused connection codes

* Removed unused code for connection restrictions

Real-time and router executors cannot handle re-using of the existing
connections within a transaction block.

Adaptive executor and COPY can re-use the connections. So, there is no
reason to keep the code around for applying the restrictions in the
placement connection logic.

Include all relevant relations in the ExtractRangeTableRelationWalker (#3135) 
We've changed the logic for pulling RTE_RELATIONs in #3109 and
non-colocated subquery joins and partitioned tables.
@onurctirtir found this steps where I traced back and found the issues.

While looking into it in more detail, we decided to expand the list in a
way that the callers get all the relevant RTE_RELATIONs RELKIND_RELATION,
RELKIND_PARTITIONED_TABLE, RELKIND_FOREIGN_TABLE and RELKIND_MATVIEW.
These are all relation kinds that Citus planner is aware of.

Remove real-time/router executors (step 1) (#3125) 
See #3125 for details on each item.

* Remove real-time/router executor tests-1

These are the ones which doesn't have '_%d' in the test
output files.

* Remove real-time/router executor tests-2

These are the ones which has in the test
output files.

* Move the tests outputs to correct place

* Make sure that single shard commits use 2PC on adaptive executor

It looks like we've messed the tests in #2891. Fixing back.

* Use adaptive executor for all router queries

This becomes important because when task-tracker is picked, we
used to pick router executor, which doesn't make sense.

* Remove explicit references to real-time/router executors in the tests

* JobExecutorType never picks real-time/router executors

* Make sure to go incremental in test output numbers

* Even users cannot pick real-time anymore

* Do not use real-time/router custom scans

* Get rid of unnecessary normalizations

* Reflect unneeded normalizations

* Get rid of unnecessary test output file

Onder Kalaci a208f8b151 Fix memory leak on ReceiveResults 
It turns out that TupleDescGetAttInMetadata() allocates quite a lot
of memory. And, if the target list is long and there are too many rows
returning, the leak becomes appereant.

You can reproduce the issue wout the fix with the following commands:

```SQL

CREATE TABLE users_table (user_id int, time timestamp, value_1 int, value_2 int, value_3 float, value_4 bigint);
SELECT create_distributed_table('users_table', 'user_id');

insert into users_table SELECT i, now(), i, i, i, i FROM generate_series(0,99999)i;

-- load faster

-- 200,000
INSERT INTO users_table SELECT * FROM users_table;

-- 400,000
INSERT INTO users_table SELECT * FROM users_table;

-- 800,000
INSERT INTO users_table SELECT * FROM users_table;

-- 1,600,000
INSERT INTO users_table SELECT * FROM users_table;

-- 3,200,000
INSERT INTO users_table SELECT * FROM users_table;

-- 6,400,000
INSERT INTO users_table SELECT * FROM users_table;

-- 12,800,000
INSERT INTO users_table SELECT * FROM users_table;

-- making the target list entry wider speeds up the leak to show up
 select *,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,*,* FROM users_table ;

Add shouldhaveshards to pg_dist_node (#2960) 
This is an improvement over #2512.

This adds the boolean shouldhaveshards column to pg_dist_node. When it's false, create_distributed_table for new collocation groups will not create shards on that node. Reference tables will still be created on nodes where it is false.

Support subqueries in HAVING (#3098) 
Areas for further optimization:
- Don't save subquery results to a local file on the coordinator when the subquery is not in the having clause
- Push the the HAVING with subquery to the workers if there's a group by on the distribution column
- Don't push down the results to the workers when we don't push down the HAVING clause, only the coordinator needs it

Fix enum add value order and pg12 (#3082) 
DESCRIPTION: Fix order for enum values and correctly support pg12

PG 12 introduces `ALTER TYPE ... ADD VALUE ...` during transactions. Earlier versions would error out when called in a transaction, hence we connect to workers outside of the transaction which could cause inconsistencies on pg12 now that postgres doesn't error with this syntax anymore.

During the implementation of this fix it became apparent there was an error with the ordering of enum labels when the type was recreated. A patch and test have been included.

Onder Kalaci 3be72ce42f Make sure that distributed functions always have the correct user 
Objectives:

(a) both super user and regular user should have the correct owner for the function on the worker
(b) The transactional semantics would work fine for both super user and regular user
(c) non-super-user and non-function owner would get a reasonable error message if tries to distribute the function

Add Citus upgrade tests with its job (#3003) 
* Add initial citus upgrade test

* Add restart databases and run tests in all nodes

* Add output for citus versions 8.0 8.1 8.2 and 8.3

* Add verify step for citus upgrade

* Add target for citus upgrade test in makefile

* Add check citus upgrade job

* Fix installation file path and add missing tar

* Run citus upgrade for v8.0 v8.1 v8.2 and v8.3

* Create upgrade_common file and rename upgrade check

* Add pg version to citus upgrade test

* Test with postgres 10 and 11 in citus upgrade tests

* Add readme for citus upgrade test

* Add some basic tests to citus upgrade tests

* Add citus upgrade mixed mode test

* Remove citus artifacts before installing another one

* Refactor citus upgrade test according to reviews

* quick and dirty rewrite of citus upgrade tests to support local execution.

I think we need to change the makefile in such a way that the tar files can be injected from the circle ci config file.

Also I removed some of the citus version checks you had to not have the requirement to pass that in separately from the pre tar file. I am not super happy with it, but two flags that need to be kept in sync is also not desirable. Instead I print out the citus version that is installed per node. This will not cause a failure if they are not what one would expect but it lets us verify we are running the expected version.

* use latest citusupgradetester in circleci

* update readme and use common alias for upgrade_common import
