Run tests against PG10 by default
What does this MR do?
This makes tests run against PG10 by default for MRs, master and nightly.
We also now run tests against:
- PG9 in nightly pipelines only (vs MR, master, and nightly before)
- PG11 in master and nightly pipelines (vs nightly pipelines before)
Relates to #208836 (closed).
Does this MR meet the acceptance criteria?
