Yup [0]. It'd be nice if we could get folks to stop using it, but that doesn't seem worth the ABI breakage, and from a couple of web searches, there doesn't seem to be much external use, anyway. IMHO letting it slowly phase out as versions go out of support is sufficient in this case. [0] https://postgr.es/m/20220418182336.GA2298576%40nathanxps13 -- nathan
