#5685 introduced the resolution of dependencies for indices. This missed support for indices on partitioned tables. This change adds support for partitioned indices to the dependency resolution code.
It turns out `whereis` is incredibly slow on WSL2 (at least on my
machine):
```
$ time whereis diff
diff: /usr/bin/diff /usr/share/man/man1/diff.1.gz
real 0m0.408s
user 0m0.010s
sys 0m0.101s
```
This command is run by our custom `diff` script, which is run for every
test file that is run. So this adds lots of unnecessary runtime time to
tests.
This changes our custom `diff` script to only call `whereis` in the
strange case that `/usr/bin/diff` does not exist.
The impact of this small change on the total runtime of the tests on WSL
is huge. As an example the following command takes 18 seconds without
this change and 7 seconds with it:
```
make -C src/test/regress/ check-arbitrary-configs CONFIGS=PostgresConfig
```

Before this commit, dumping wait edges can only be used for
distributed deadlock detection purposes. With this commit,
we open the possibility that we can use it for any backend.
CREATE FUNCTION command together with it's dependencies.
If the function depends on any nondistributable object,
function will be created only locally. Parameterless
version of create_distributed_function becomes obsolete
with this change, it will deprecated from the code with a subsequent PR.
* When a worker tried to create a collation which had a dependency in the same worker node,
it would cause a deadlock, now it throws the correct "not a coordinator" error.

DESCRIPTION: Implement TEXT SEARCH CONFIGURATION propagation
The change adds support to Citus for propagating TEXT SEARCH CONFIGURATION objects. TSConfig objects cannot always be created in one create statement, and instead require a create statement followed by many alter statements to get turned into the object they should represent.
To support this we add functionality to the worker to create or replace objects based on a list of statements. When the lists of the local object and the remote object correspond 1:1 we skip the creation of the object and simply mark it distributed. This is especially important for TSConfig objects as initdb pre-populates databases with a dozen configurations (for many different languages).
When the user creates a new TSConfig based on the copy of an existing configuration there is no direct link to the object copied from. Since there is no link we can't simply rely on propagating the dependencies to the worker and send a qualified
We check for metadata consistency across the cluster in the test
isolation_metadata_sync_vs_all. However, some earlier tests in
enterprise repo leave invalid pg_dist_node entries in the worker nodes
that have Oid values for already dropped role objects.
To remedy that, I suggest that we move the test to earlier in the
schedule, thereby making the tests pass for the time being. We should
later introduce metadata checking either in a new isolation test or by
moving this test later in the schedule. However, we should do that after
we fix the underlying issue.
The low-level StoreAllActiveTransactions() function filters out
backends that exited.
Before this commit, if you run a pgbench, after that you'd still
see the backends show up:
```SQL
select count(*) from get_global_active_transactions();
┌───────┐
│ count │
├───────┤
│ 538 │
└───────┘
```
After this patch, only active backends show-up:
```SQL
select count(*) from get_global_active_transactions();
┌───────┐
│ count │
├───────┤
│ 72 │
└───────┘
```
DESCRIPTION: Prevent Citus table functions from being called on shards
The operations that guard against using shards are:
* Create Local Table
* Create distributed table (which affects reference table creation as well).
* I used a `ErrorIfRaltionIsKnownShard` instead of `ErrorIfIllegallyChangingKnownShard`.
`ErrorIfIllegallyChangingKnownShard` allows the operation if `citus.enable_manual_changes_to_shards`,
but I am not sure if it ever makes sense to create a distributed, reference, or citus local table out of a shard.
I tried to go over the code to identify other UDF-s where shards could be illegaly changed, but I could not find any other.
My knowledge of the codebase is not solid enough for me to say for sure.
