get_pg_version() is able to return a version number, that can be used for comparisons based on PG_VERSION_NUM. A macro is added to convert the result to a major version number, to work with PG_MAJORVERSION_NUM. It is possible to pass to the routine an optional argument, where the contents retrieved from PG_VERSION are saved. This requirement matters for some of the frontend code (one example: pg_upgrade wants that for tablespace paths with a version number strictly older than v10). This will be used by a set of follow-up patches, to be consumed in various frontend tools that duplicate a logic similar to do what this new routine does, like: - pg_resetwal - pg_combinebackup - pg_createsubscriber - pg_upgrade This routine supports both the post-v10 version number and the older flavor (aka 9.6), as required at least by pg_upgrade.
