size limits on insert/copy/etc

От

Дата:
I'm trying to add large text items to a table (field declared as type
text). PQSendQuery can't take more than 8192 bytes.That's OK. But COPY
also complains that tuples of 29896 bytes are too big (trying to copy
from a file). So how do I get big text fields into a table? Do I have to
make them large objects? (And, if so, in what sense is the text field of
"unlimited size"?) Or am I just missing something simple?

Many thanks in advance for any advice...

Unfortunately tuples cannot be bigger than 8k. Many of us I think look
forward to the day when this restriction doesn't apply (it is on the
to-do list), but at this point in time 8k is the limit.

Large objects will work, but they have other problems that make them
fairly impractical.
