Historically we have been testing with the 'latest' version of libpq
when the CI images were build. This has the downside that rebuilding the
images often break our tests due to different errors returned from
libpq.
With this change we will actually test with a stable version of libpq
that is based on the postgres minor version that we test against.
This will make it easier to maintain postgres images over time, as well
as running _all_ tests locally, where we change libpq in sync with the
postgres server version.
use RecurseObjectDependencies api to find if an object is citus depended
make vanilla tests runnable to see if citus_depended function is working correctly
citus_locks combines the pg_locks views from all nodes and adds
global_pid, nodeid, and relation_name. The columns of citus_locks don't
change based on the Postgres version, however the pg_locks's columns do.
Postgres 14 added one more column to pg_locks (waitstart timestamptz).
citus_locks has the most expansive column set, including the newly added
column. If citus_locks is queried in a Postgres version where pg_locks
doesn't have some columns, the values for those columns in citus_locks
will be NULL
DESCRIPTION:
This PR extends support for Partitioned and Columnar tables in blocking 'citus_split_shard_by_split_points' workflow.
Columnar Support : No special handling required. Just removing checks that fails split for columnar table and adding test coverage.
Partitioned Table Support :
Skip copying of parent table as they are empty, The partitions contain data and are treated as co-located shards that will be copied separately.
Attach partitions to parent on destination after inserting new shard metadata and before creating foreign key constraints.
MISC:
Fix Bug #4949 where Blocking shard moves fails if there is a foreign key between partitioned distributed tables (from child to parent).
TEST:
Added new test 'citus_split_shards_columnar_partitioned' for splitting 'partitioned' and 'columnar + partitioned' table.
Added new test 'shard_move_constraints_blocking' to add coverage for shard move bug fix.
Updated test 'citus_split_shard_by_split_points_negative' to allow columnar and partitioned table.

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

* Fixed deadlock for unqualified vacuum when there is only 1 worker,
* Supported lock_skipped for vacuum.
