I am guessing that the OP tried to put a literal NUL character
into the COPY data.  A bytea value in COPY data needs to be
text-encoded as per one of the alternatives explained in the
manual.  Alternatively, you could jump through the hoops involved
in sending binary COPY data.

This is not about loading data into a "bytea", but into a "text", "varchar" or
"char" column.  Check again.

Hi,

I have a table with bytea column and trying to load the data using copy
command.  But Copy command is failing with "ERROR: invalid byte sequence
for encoding UTF8: 0x00. Why postgresql is failing to load when data
contains 0x00. How to resolve this error ? any workaround to load the data
with 0x00 values ?

Please advise. Thank you very much.

Regards,
Kiran
