Обсуждение: Bulk COPY end of copy delimiter
Today while trying to do a bulk COPY of data into a table, the process aborted with the following error message: ERROR: end-of-copy marker corrupt CONTEXT: COPY tbl_logged_event, line 178519: "606447014,1492,2005-02-24 03:16:14,2005-02-23 20:27:48,win_applog,,error,adsmclientservice,nt author..." Googling the error, we found reference to the '\.' (backslash-period) being an "end-of-copy marker". Unfortunately, our data contains the backslash-period character sequence. Is there any know fix or workaround for this condition? We're using Postgresql 7.3.9 and also running tests on an 8.0.1 system.

Any sequence \. in COPY input data should be escaped as \\. If this data was generated by pg_dump then its a problem, but I haven't seen any other reports of this. Can I assume that you've generated the data for bulk load yourself? If so, there is discussion of escaping characters here: http://www.postgresql.org/docs/8.0/static/sql-copy.html. Gavin
Your assumption is correct. The data was generated out of a DB2 database,
and uses commas as field delimiters.
Thank you for the workaround,
--- Steve

Any sequence \. in COPY input data should be escaped as \\. If this data
was generated by pg_dump then its a problem, but I haven't seen any other
reports of this. Can I assume that you've generated the data for bulk load
yourself? If so, there is discussion of escaping characters here:
