Similar to #5897, one more step for running Citus with PG 15.
This PR at least make Citus run with PG 15. I have not tried running the tests with PG 15.
Shmem changes are based on 4f2400cb3f
Compile breaks are mostly due to #6008
This is a continuation of a refactor (with commit sha
2b7cf0c097) that aimed to use Citus helper
UDFs by default in iso tests.
PostgreSQL isolation test infrastructure uses some UDFs to detect
whether concurrent sessions block each other. Citus implements
alternatives to that UDF so that we are able to detect and report
distributed transactions that get blocked on the worker nodes as well.
We needed to explicitly replace PG helper functions with Citus
implementations in each isolation file. Now we replace them by default.
* Support upgrade and downgrade and separate columnar as citus_columnar extension

PostgreSQL isolation test infrastructure uses some UDFs to detect

* Added more regression tests for more vacuum options,
* Fixed deadlock for unqualified vacuum when there is only 1 worker,
* Supported lock_skipped for vacuum.
This PR makes all of the features open source that were previously only
available in Citus Enterprise.
Features that this adds:
1. Non blocking shard moves/shard rebalancer
(`citus.logical_replication_timeout`)
2. Propagation of CREATE/DROP/ALTER ROLE statements
3. Propagation of GRANT statements
4. Propagation of CLUSTER statements
5. Propagation of ALTER DATABASE ... OWNER TO ...
6. Optimization for COPY when loading JSON to avoid double parsing of
the JSON object (`citus.skip_jsonb_validation_in_copy`)
7. Support for row level security
8. Support for `pg_dist_authinfo`, which allows storing different
authentication options for different users, e.g. you can store
passwords or certificates here.
9. Support for `pg_dist_poolinfo`, which allows using connection poolers
in between coordinator and workers
10. Tracking distributed query execution times using
citus_stat_statements (`citus.stat_statements_max`,
`citus.stat_statements_purge_interval`,
`citus.stat_statements_track`). This is disabled by default.
11. Blocking tenant_isolation
12. Support for `sslkey` and `sslcert` in `citus.node_conninfo`
We already have tests relying on citus_finalize_upgrade_to_citus11().
Now, adjust those to rely on citus_finish_citus_upgrade() and
always call citus_finish_citus_upgrade().
