Onder Kalaci f8417d184c 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 ;

 ```

Bump Citus version to 9.0.0 2019-10-07 21:00:01 +03:00

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

Disallow distributed functions for functions depending on an extension (#3049) 
DESCRIPTION: Disallow distributed functions for functions depending on an extension

Functions depending on an extension cannot (yet) be distributed by citus. If we would allow this it would cause issues with our dependency following mechanism as we stop following objects depending on an extension.

By not allowing functions to be distributed when they depend on an extension as well as not allowing to make distributed functions depend on an extension we won't break the ability to add new nodes. Allowing functions depending on extensions to be distributed at the moment could cause problems in that area.

Propagate CREATE OR REPLACE FUNCTION to workers for distributed functions (#3043) 
DESCRIPTION: Propagate CREATE OR REPLACE FUNCTION

Distributed functions could be replaced, which should be propagated to the workers to keep the function in sync between all nodes.

Due to the complexity of deparsing the `CreateFunctionStmt` we actually produce the plan during the processing phase of our utilityhook. Since the changes have already been made in the catalog tables we can reuse `pg_get_functiondef` to get us the generated `CREATE OR REPLACE` sql.

Hanefi Onaldi 66b9f2e887 Deparsing and qualifiying for FUNCTION/PROCEDURE statements (#3014) 
This PR aims to add all the necessary logic to qualify and deparse all possible `{ALTER|DROP} .. {FUNCTION|PROCEDURE}` queries.

As Procedures are introduced in PG11, the code contains many PG version checks. I tried my best to make it easy to clean up once we drop PG10 support.


Here are some caveats:
- I assumed that the parse tree is a valid one. There are some queries that are not allowed, but still are parsed successfully by postgres planner. Such queries will result in errors in execution time. (e.g. `ALTER PROCEDURE p STRICT` -> `STRICT` action is valid for functions but not procedures. Postgres decides to parse them nevertheless.)

Marco Slot 2868e02a3d Implement SELECT function call delegation. 
When a function is marked as colocated with a distributed table,
we try delegating queries of kind "SELECT func(...)" to workers.

We currently only support this simple form, and don't delegate
forms like "SELECT f1(...), f2(...)", "SELECT f1(...) FROM ...",
or function calls inside transactions.

As a side effect, we also fix the transactional semantics of DO blocks.
Previously we didn't consider a DO block a multi-statement transaction.
Now we do.

Set default threshold on get_rebalance_table_shards_plan to 0, like rebalance_table_shards (#3039) 
In this PR the default `threshold` of `rebalance_table_shards` was set to 0: https://github.com/citusdata/shard_rebalancer/pull/73
However, the default for get_rebalance_table_shards_plan was not updated. This
can cause the confusing situation where the actual steps run by
`rebalance_table_shards` are not the same as the ones returned by
`get_rebalance_table_shards_plan`.

Marco Slot 32a11bdf6c Return early for common commands in the utility hook (#3031) 
We started copying parse trees by default further on in `multi_ProcessUtility`. That's not a problem for maintenance command, but might register for things like `PREPARE` and `EXECUTE`, which might happen thousands of times per second. Add a few common commands to the check at the start.
