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.

Jelte Fennema 4ba5619bb2 Make implicit declarations and wrong return types hard errors 
This makes three warnings hard errors:

1. `implicit-int`
> Warn when a declaration does not specify a type.

2. `implicit-function-declaration`
> Give a warning whenever a function is used before being declared.

3. `return-type`
> Warn whenever a function is defined with a return type that defaults to
> "int".  Also warn about any "return" statement with no return value in
> a function whose return type is not "void" (falling off the end of the
> function body is considered returning without a value).
>
> For C only, warn about a "return" statement with an expression in a
> function whose return type is "void", unless the expression type is
> also "void".

The compiler behaviour when these warnings occur is not the behaviour
the developer expects. So even during development it makes sense that
they are errors.

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.

Clean old citus install before installing extension (#3134) 
One case where this would have been useful recently was when we changed
the `citus--9.0-1--9.1-1.sql` file to `citus--9.0-2--9.1-1.sql`. If you
had the old file installed it would never be cleaned. Any changes in
the 9.0-2 version would not be applied, because postgres tries to find
the shortest migration path, so it would always run the 9.0-1--9.1-1
version, because then it could skip 9.0-1--9.0-2.

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

Jelte Fennema 96b8c36723 Better check for compiler flag capability 
When adding a `-Wno-some-error` flag, instead of trying to check for
`-Wno-some-error` support this checks for `-Wsome-error` support.
This is done because currently there's the a problem when compiling
citus with `./configure CFLAGS=-Werror`. If there's a warning (which is
then converted to an error) in addition to this error, the output will contain
the following message with GCC 7:

```
cc1: error: unrecognized command line option ‘-Wno-gnu-variable-sized-type-not-at-end’ [-Werror]
```

This is because of the following behaviour of GCC in case of unknown warnings:

> When an unrecognized warning option is requested (e.g., -Wunknown-warning), GCC
> emits a diagnostic stating that the option is not recognized.  However, if the
> -Wno- form is used, the behavior is slightly different: no diagnostic is
> produced for -Wno-unknown-warning unless other diagnostics are being produced.
> This allows the use of new -Wno- options with old compilers, but if something
> goes wrong, the compiler warns that an unrecognized option is present.

By changing the check to `-Wsome-error`, the check will actually fail
when the warning is not supported. Instead of silently being ignored
when checking, but then coming up when another error happens.

Add extra foreach convenience macros (#3117) 
This completely hides `ListCell` to the user of the loop

Example usage:
```c
WorkerNode *workerNode = NULL;

foreach_ptr(workerNode, workerNodeList) {
	// Do stuff with workerNode
}
```

Instead of:
```c
ListCell *workerNodeCell = NULL;

foreach(cell, workerNodeList) {
    WorkerNode *workerNode = lfirst(workerNodeCell);
	// Do stuff with workerNode
}

Fix memory leak on ReceiveResults
 2019-10-22 17:29:52 +02:00
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
