  1. feat: disable WAL archiving during import bootstrap 

    When using the import facility of the initdb bootstrap method in a job,
optimize the PostgreSQL instance for the sole duration of the job, by setting
the following GUCs:

- `archive_mode` to `off`
- `fsync` to `off`
- `full_page_writes` to `off`
- `wal_level` to `minimal`

Then, restore the configuration and invoke `initdb --sync-only` before the end
of the import job.

Closes #3741
