Add filtering capability for cross-version pg_upgrade tests
This commit expands the TAP tests of pg_upgrade when running these with
different major versions for the "old" cluster (to-be-upgraded) and the
"new" cluster (upgraded-to), by backporting some of the buildfarm
facilities directory into the script:
- Remove comments from the dump files, avoiding version-dependent
information.
- Remove empty lines from the dump files.
- Use --extra-float-digits=0 in the pg_dump command, when using an "old"
cluster with version equal to or lower than v11.
- Use --wal-segsize and --allow-group-access in initdb only when the
"old" cluster is equal to or higher than v11.
This allows the tests to pass down to v14 with the main regression test
suite, while v9.5~13 still generate some diffs, but these are minimal
compared to what happened before this commit. Much more could be done,
especially around dump differences with function and procedures (these
can also be avoided with direct manipulation of the dumps loaded, for
example, in a way similar to the buildfarm), but at least the basics are
in place now.
