Marc G. Fournier 476ef10913 This patch can be installed as part of 1.02.1 so people can properly ... pg_dump and load to 2.0. I haven't gotten any feedback on whether people want it, so I am submitting it for others to decide. I would recommend an install in 1.02.1. I had said that the 2.0 pg_dump could dump a 1.02.1 database, but I was wrong. The copy is actually performed by the backend, and the 2.0 database will not be able to read 1.02.1 databases because of the new system columns. This patch does several things. It copies nulls out as \N, so they can be distinguished from '' strings. It fixes a problem where backslashes in the input stream were not output as double-backslashes. Without this patch, backslashes copied out were deleted upon input, or interpreted as special characters. Third, input is now terminated by backslash-period. This can not be part of a normal input stream. I tested this by creating a database with all sorts of nulls, backslash, and period fields and dumped the database and reloaded into a new database and compared them.
