Could you elaborate that a bit? It sounds interesting but I do not get what you mean by: "bytea deserialization": Do you mean from an escaped string back to real binary data? Does that apply to my case (I use PGexecParam and have the Format arg set to 1, binary) ? "I/O bound": What do you mean by that? > You can speed things up by sending the data in binary, by passing > approriate parameters to PQexecParams(). Do you mean the Format arg =1 ? If not, what is appropriate here?
