Re: proposal - get_extension_version function

Hi

I try to write a safeguard check that ensures the expected extension version for an extension library.

Some like

const char *expected_extversion = "2.5";

...

extoid = getExtensionOfObject(ProcedureRelationId, fcinfo->flinfo->fn_oid));

extversion = get_extension_version(extoid);

if (strcmp(expected_extversion, extversion) != 0)

   elog(ERROR, "extension \"%s\" needs \"ALTER EXTENSION %s UPDATE\",

          get_extension_name(extversion),

          get_extension_name(extversion)))

Currently the extension version is not simply readable - I need to read directly from the table.

Notes, comments?

Regards

Pavel
