Hi Fabien, > I think that the probability of getting these useful things into pg is > alas small. In the mean time, you may package and register it as an > extension? I aimed to close the asymmetry between bit vector operations (they also offer xor/and/etc.) and bytea operations. My code is more or less a 1:1 copy of the corresponding bit vector operations (in fact, just a tiny bit easier, since bytea is byte-aligned, wheres bit vectors aren't).
I just wanted to dump the code here, given that Tom suggested (in 2006) such an implementation might be a useful addition to bytea. But I won't feel offended in any way if the code won't be merged. Cheers, Christian
