It is important that any external modules are also binary compatible, though this cannot be checked by pg_upgrade. Pg_upgrade does its best to make sure the old and new clusters are binary-compatible, e.g., by checking for compatible compile-time settings, including 32/64-bit binaries. (The community will attempt to avoid such situations.) If a future major release ever changes the data storage format in a way that makes the old data format unreadable, pg_upgrade will not be usable for such upgrades. pg_upgrade uses this fact to perform rapid upgrades by creating new system tables and simply reusing the old user data files. Major PostgreSQL releases regularly add new features that often change the layout of the system tables, but the internal data storage format rarely changes. ![]() It is not required for minor version upgrades, e.g., from 12.7 to 12.8 or from 14.1 to 14.5. Pg_upgrade (formerly called pg_migrator) allows data stored in PostgreSQL data files to be upgraded to a later PostgreSQL major version without the data dump/restore typically required for major version upgrades, e.g., from 12.14 to 13.10 or from 14.9 to 15.5.
