Hi Lee,
Thanks for the suggestion. I should have mentioned in my original
message that as per your suggestion and the suggestion in the
documentation, I have tried escaping the backslashes. When I do this,
I get the error:
ERROR: invalid input syntax for type bytea
I tried also doing
INSERT INTO myTable VALUES (...,
E'\\x15\\x1C\\x2F\\x00\\x02...'::bytea, ...) ;
but get the same errors.
I think i see another problem with your query. You should convert to
three-digit octal (something like \\001\\002...) not \\x01 (hex?).
Hi Jan,
Thanks, I think I finally see what's happening here (and understand the
docs) - the bytea type has its own string-serialization (escape format)
_separate_ from postgresql's normal string literal escaping. So while
E'\xC0' is postgresql serialization of a string containing whatever
character maps from 0xC0 in the current encoding, that byte cannot
directly go into a bytea. Instead, I need to have a doubly-escaped octal
(specifically) string so that the first escape generates a string like
\000\001\002 which the bytea processor (somewhere) then re-parses as a
sequence of bytes.
Would be nice if the bytea parser understood hex representation too, but
beggars can't be choosers :)
thanks for the help,
Lee
Jan
