Answer 1

You can work around this by piping the file through a program. For example I just used this to copy from a 24GB file on Windows 10 and PostgreSQL 11.

copy t(c,d) from program 'cmd /c "type x:\path\to\file.txt"' with (format text);

This copies the text file file.txt into the table t, columns c and d.

The trick here is to run cmd in a single command mode, with /c and telling it to type out the file in question.
