Ok, See v.2 in attachment.
Generally, the patch looks good to me. I have couple of questions.
1) Is it intended to switch all in-core libraries to use PG_MODULE_MAGIC_EXT()?
I haven't such intention. Just wanted to demonstrate how it might work.
2) Once we have module version information, it looks natural to
specify the required version for dependant objects, e.g. SQL-funcions
implemented in shared libraries. For instance,
CREATE FUNCTION ... AS 'MODULE_PATHNAME' LANGUAGE C module_version >= '1.0';
Just to be clear. You want this stuff to let the core manage situations
of stale binaries and throw an error like the following:
"No function matches the given name, argument types and module version"
Do I understand you correctly?
It may make sense, but I can't figure out a use case. Could you describe
at least one example?
