I think you might be confusing PQescapeString (intended for text) with
PQescapeBytea (intended for binary data). We do not support any text
encodings that require embedded zeroes, and are unlikely to do so
anytime soon. (Had anyone suggested this as a design goal when we were
doing the recent FE/BE protocol redesign, perhaps the protocol wouldn't
still rely on null-terminated strings. But no one did and it's too late
now.)
