Perhaps my understanding of the 'encode' function is incorrect, but I
was under the impression that I could do something like:
SELECT lower(encode(bytes, 'escape')) FROM mytable;
as it sounded like (from the manual) that 'encode' would return valid
ASCII, with all the non-ascii bytes hex escaped. When I have the byte
0x8a, however, I get the error:
ERROR: invalid byte sequence for encoding "UTF8": 0x8a
I have the sneaking suspicion that I am missing something, so please
correct me if I am wrong. If I am wrong, is there a better way to
lowercase all the ascii characters in a bytea string?
Here is a simple way to recreate this:
CREATE TABLE mytable (bytes BYTEA);
INSERT INTO mytable VALUES (E'212');
SELECT lower(encode(bytes, 'escape')) FROM mytable;
Thanks
