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:
- PG16 removed logic for converting a table to a view
Relevant PG commit:
b23cd185fd
b23cd185fd5410e5204683933f848d4583e34b35
- Fix changed error message in certificate verification
Relevant PG commit:
8eda731465
8eda7314652703a2ae30d6c4a69c378f6813a7f2
- Fix backend type order in tests
Relevant PG commit:
0c679464a8
0c679464a837079acc75ff1d45eaa83f79e05690
- Reduce log level to omit extra NOTICE in create collation in PG16
Relevant PG commit:
a14e75eb0b
a14e75eb0b6a73821e0d66c0d407372ec8376105
That commit made LOCALE parameter apply regardless of the
provider used, and it printed the following notice:
NOTICE: using standard form "und-u-ks-level2" for ICU locale "@colStrength=secondary"
We omit this notice to omit output change between pg versions.
- Fix columnar_memory test
TopMemoryContext now has more children contexts
Possible relevant PG commit:
9d3ebba729
9d3ebba729ebaf5882a92f0f5f662a3312037605
memusage is now around 8.5 MB, whereas it was less than 8MB before.
To avoid differences between PG versions, I changed the test to compare
to less than 9 MB. It still reflects very well the improvement from
28MB.
- Alternative test output for GRANTOR values in pg_auth_members
grantor changed in PG16
Relevant PG commit:
ce6b672e44
ce6b672e4455820a0348214be0da1a024c3f619f
- Remove redundant grouping columns from our tests
Relevant PG commit:
8d83a5d0a2
8d83a5d0a2673174dc478e707de1f502935391a5
- Fix tests with different order in Filters
Relevant PG commit:
2489d76c49
2489d76c4906f4461a364ca8ad7e0751ead8aa0d
More PG16 compatibility commits are coming soon ...
Sometimes in CI the columnar_memory test was using slightly more memory
than expected.
```diff
SELECT CASE WHEN 1.0 * TopMemoryContext / :top_post BETWEEN 0.98 AND 1.02 THEN 1 ELSE 1.0 * TopMemoryContext / :top_post END AS top_growth
FROM columnar_test_helpers.columnar_store_memory_stats();
--[ RECORD 1 ]-
-top_growth | 1
+-[ RECORD 1 ]------------------
+top_growth | 1.0206132116232119
-- before this change, max mem usage while executing inserts was 28MB and
```
This PR changes the expectation to be slightly higher, such that this
random increase in memory usage doesn't cause a flaky test.
Failing test: https://app.circleci.com/pipelines/github/citusdata/citus/26256/workflows/c0870f66-3346-4f8d-a1d3-36dfd7c98289/jobs/743028
Sometimes the columnar_memory test fails in CI with the following error:
```diff
SELECT 1.0 * TopMemoryContext / :top_post BETWEEN 0.98 AND 1.02 AS top_growth_ok
FROM columnar_test_helpers.columnar_store_memory_stats();
-[ RECORD 1 ]-+--
-top_growth_ok | t
+top_growth_ok | f
-- before this change, max mem usage while executing inserts was 28MB and
```
This is almost certainly a harmless failure that simply requires bumping
the margin a little bit. However, it's impossible to say with the
current output. I was unable to reproduce this on-demand on my local
machine or even in CI. So this changes the test to include the actual
value difference in the size of TopMemoryContext when it's outside the
expected range. Then next time it fails we at least have some
information about why.
Example of failing test: https://app.circleci.com/pipelines/github/citusdata/citus/25966/workflows/d472a57b-419a-4f33-b8bc-2e174a98d4d6/jobs/730576
