The tgeometry and tgeography types only allow discrete or stepwise interpolation between instants, while the other three also allow linear interpolation. Refer to the MobilityDB 1.3 documentation for more information about these new types. Please notice that the new types tcbuffer, tpose, and trgeometry are still in development and are considered experimental. In addition, the API of MobilityDB and MEOS was extended with new functionality and streamlined to improve usability. Finally, version 1.3 also enables the latest versions PostgreSQL 18 and PostGIS 3.6.0. For all these reasons, the binary format of the temporal types have changed from version 1.2 to 1.3 and thus a backup and restore is needed for migrating to the newer version 1.3 of MobilityDB. Best regards, The MobilityDB Team
