I guess that when you say NULL you don't mean SQL NULL, but
the byte E'\\000', right? The rest of my E-Mail is based on
that assumption.

When calling PQexecParams to store a bytea, either set
paramFormats[i] to 0 (text) and use escape sequences as above,
or set paramFormats[i] to 1 (binary) and dont't forget to set
paramLengths[i] to the length of the binary data.

Large Objects.
But there's nothing wrong with bytea.
