* MySQL 8.0.11 changed the `GeometryCollection` data type name to `GeomCollection`, with the latter being the preferred name.
* MySQL 8.0.17 removed support for the display width attribute for integer data types. Previously, default display width of 20 digits was used: `BIGINT(20)`.
The affected tests now check the MySQL server version and use the appropriate data types.
This leaves one unresolved failure on MySQL 8.0.17+ to be addressed in the future, caused by the same `BIGINT` display width discrepancy coming from `wp_get_db_schema()`.
