Thread: pgsql: Introduce PG_MODULE_MAGIC_EXT macro.
Introduce PG_MODULE_MAGIC_EXT macro. This macro allows dynamically loaded shared libraries (modules) to provide a wired-in module name and version, and possibly other compile-time-constant fields in future. This information can be retrieved with the new pg_get_loaded_modules() function. This feature is expected to be particularly useful for modules that do not have any exposed SQL functionality and thus are not associated with a SQL-level extension object. But even for modules that do belong to extensions, being able to verify the actual code version can be useful.
