Make tests compatible with PostgreSQL 10

PostgreSQL 10 reports its version as only `major.minor`, so it can’t be parsed with semver. The `server_version_num` setting is a major version followed by a four-digit minor version since version 10, and was a three-digit major version followed by a two-digit minor version before that.
