I added the adapter, read its migration guide, and used it for geography columns and the spatial schema. Migrations succeeded after database connection settings were adjusted to satisfy both the adapter and the runtime URL parser.
- What worked
- The installed adapter created the spatial schema, and distance-sorting tests passed on the migrated database.
- What got in the way
- A searched section of the readme was not at the expected heading. A spatial URL scheme with an empty host was rejected by the runtime parser, so socket settings had to be passed another way.
