So I was wondering if there's any interest in having a similar API > for int64 type, as well. This has been discussed before, and we've felt that it wasn't worth the additional code duplication. I would not favor approaching this with the mindset of lets-copy-and-paste-all-the-code. However: it might be interesting to think about having just two underlying implementations, one for 32-bit datums and one for 64-bits, with the existing APIs becoming macros-with-casts wrappers around the appropriate one of those. That line of attack might lead to physically less code not more. The devil's in the details though. regards, tom lane
