Subject: pgsql: Introduce PG_MODULE_MAGIC_EXT macro.
Date: Wed, 26 Mar 2025 15:11:32 +0000
Message-ID: <[email protected]> (raw)
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.
