Re: COPY FROM query.

"Having said that, if I switch it to a forward slash it works without

Yes, but PostgreSQL uses a back-slash as an escape character, which needs to
be used to escape itself at an application level before the O/S gets to deal
with it :)

If this is the case, it is strange that the first copy statement works
as that is also only using a single backslash.

Having said that, if I switch it to a forward slash it works without
error... odd, given that weenblows standard is backslash.
