Yes, sure, I know that, but the matter is - the fields are mostly
textual ones, and can hold just about any text, so it's hard to choose
a right delimiter for fields, you know ;) I though I'd eliminate the
problem by using zero-byte for a field delimiter, but apparently COPY
FROM accepts only "printable" symbols as delimiters...
Another solution would be to escape potential delimiter everywhere in
the text fields, but that also requires using external tools... I had
a hope that COPY FROM can be persuaded to use some non-printable
character in its WITH DELIMITER clause, but apparently this is not the
case...
