Thanks, Adrian,

I’ll try a windows compile of pgloader sometime during the holidays. It’s true that I already have a solution (export <= 65000 row chunks, import into Excel, export via Excel puts quotes around the text columns), but something faster and more efficient would really help in this case.

A suggestion,give pgloader a look;

If I am following you it might already have the solution to the multi-line
problem. In particular read the History section of the docs.
