Re: Importing CSV File

The trick is to tell postgres where the data ends with \.

From http://www.postgresql.org/docs/9.3/interactive/sql-copy.html

End of data can be represented by a single line containing just
backslash-period (\.). An end-of-data marker is not necessary when reading
from a file, since the end of file serves perfectly well; it is needed only
when copying data to or from client applications using pre-3.0 client
protocol.

So if you can somehow add the \. to the end of your data before the
extraneous \r\n 's , it will solve your problem.

The following works as a test:

CREATE TABLE junk
(
pkey integer,
jdata varchar(10),
CONSTRAINT junk_pk PRIMARY KEY (pkey)
);

TRUNCATE TABLE junk;
COPY junk FROM '/tmp/junk.data' WITH CSV;

contents of /tmp/junk.data:
-------------------------------------------------------------------
1,'junk1'
2,'junk1'
3,'junk1'
\.
garbage data1
more garbage
....
blah
enough alread
