CopyManager only delimit once

Question

I'm trying to import a password list into a postgresql database. Is there any way to delimit a line only once or only at the first occurrence of the delimiter character?

Data to import:

demo@mail.ru:123
demo@mail.de:ab:c

My importing code:

import org.postgresql.copy.CopyManager;
import org.postgresql.core.BaseConnection;

CopyManager copyManager = new CopyManager((BaseConnection) connection);
FileReader fileReader = new FileReader(file);
copyManager.copyIn("COPY db FROM STDIN DELIMITER ':' ", fileReader);

This code will fail at the second example as it contains two : characters. Any ideas or suggestions to solve this?

Thanks for any help!

Suggestion to escape second : :

org.postgresql.util.PSQLException: ERROR: extra data after last expected column
  Where: COPY pwned, line 1: "user@demo.pl:123":abc"

Answer 1

The PostgreSQL COPY command supports the ESCAPE option. Use this together with escaping the colons in your data. Since ESCAPE defaults to QUOTE which defaults to " , change your data to this:

demo@mail.ru:123
demo@mail.de:ab":c

Also DELIMITER must be a single one-byte character. Your SQL should be

COPY db FROM STDIN DELIMITER ':'
