This commit is in the series of PG16 compatibility commits. It makes some changes
to our tests in order to be compatible with the following in PG16:
- Fix multi_subquery_in_where_reference_clause test
somehow PG got rid of the outer join
(e.g., explain doesn't show outer joins),
hence we can pushdown the subquery.
Changing to users_reference_table
- Fix unqualified column names for views in PG16
Relevant PG commit:
47bb9db759
47bb9db75996232ea71fc1e1888ffb0e70579b54
- Fix global_cancel test
Error wording and detail changed
Relevant PG commit:
2631ebab7b
2631ebab7b18bdc079fd86107c47d6104a6b3c6e
- Fix local_table_join_test with lateral subquery
Possible relevant PG commit:
ae89129aa3
ae89129aa3555c263b8c3ccc4c0f1ef7e46201aa
I removed the where clause and the limit count error was hit again.
With the where clause the query unexpectedly works.
- Fix test outputs
Relevant PG commits:
-- 1349d2790b
-- f4c7c410ee
For multi_explain and multi_complex_count_distinct there were too many places
touched so I just added an alternative test output.
For the other tests I modified the problematic parts.
More PG16 compatibility commits are coming soon ...
I observed a flaky test output
[here](https://app.circleci.com/pipelines/github/citusdata/citus/32692/workflows/32464a22-7fd6-440a-9ff7-cfa62f9ff58a/jobs/1126144)
and added `ORDER BY` clauses to similar queries in the failing test
file.
```diff
SELECT pg_identify_object_as_address(classid, objid, objsubid) from pg_catalog.pg_dist_object where objid IN('viewsc.prop_view3'::regclass::oid, 'viewsc.prop_view4'::regclass::oid);
pg_identify_object_as_address
---------------------------------
- (view,"{viewsc,prop_view3}",{})
(view,"{viewsc,prop_view4}",{})
+ (view,"{viewsc,prop_view3}",{})
(2 rows)
```
With this commit we've started to propagate sequences and shell
tables within the object dependency resolution. So, ensuring any
dependencies for any object will consider shell tables and sequences
as well. Separate logics for both shell tables and sequences have
been removed.
Since both shell tables and sequences logic were implemented as a
part of the metadata handling before that logic, we were propagating
them while syncing table metadata. With this commit we've divided
metadata (which means anything except shards thereafter) syncing
logic into multiple parts and implemented it either as a part of
ActivateNode. You can check the functions called in ActivateNode
to check definition of different metadata.
Definitions of start_metadata_sync_to_node and citus_activate_node
have also been updated. citus_activate_node will basically create
an active node with all metadata and reference table shards.
start_metadata_sync_to_node will be same with citus_activate_node
except replicating reference tables. stop_metadata_sync_to_node
will remove all the metadata. All of those UDFs need to be called
by superuser.

This commit brings following features:
Foreign key support from citus local tables to reference tables
* Foreign key support from reference tables to citus local tables
(only with RESTRICT & NO ACTION behavior)
* ALTER TABLE ENABLE/DISABLE trigger command support
* CREATE/DROP/ALTER trigger command support
and disallows:
* ALTER TABLE ATTACH/DETACH PARTITION commands
* CREATE TABLE <postgres table> ATTACH PARTITION <citus local table>
commands
* Foreign keys from postgres tables to citus local tables
(the other way was already disallowed)
for citus local tables.
