hello,

does anyone have a C implementation of xor(bytea,bytea)?

i need to xor aggregate the results of a digest.

an xor operator for bytea would be great too, but i'd be happy with
just the function.

i've searched and found past posts about xor'ing text, or bit <->
bytea casting.  it seemed the general developer attitude was that xor
operators for bytea might be appropriate, but i haven't found a
materialization of that.

thanks,
tavin
