I did some research on this and it turns out it is one of our TODO
items. It is:
o Allow COPY FROM ... CSV to interpret newlines and carriage
returns in data
This would require major refactoring of the copy source code.
We are actually careful to warn people who dump out data with newlines
in CSV format:
test=> insert into t values (4, 'lkjasdf
test'> lkjasdf
test'>
test'>
test'>
test'> aaaa');
INSERT 542038 1
test=> copy t to '/bjm/3' with null as '' csv quote as '"';
WARNING: CSV fields with embedded linefeed or carriage return characters might not be able to be reimported
COPY
Someone has come up with a patch which might allow this so it might work
in 8.1.
I am attaching a reproducable case of your report.
