I am trying to copy out about 50G of data.
When I used copy table X to '/opt/x.csv' using delimiters ','
with null as '';
and x.csv reached a size of 2G, I got the error message that the
file was too big.
How can I get around this without moving things out in smaller
packages (more time-consuming)?

It's a matter of the underlaying operating system which doesnt allow
files bigger than 2G. You can send your output in a pipe and split it
on several files.
see 'man split' for details.
This kind of problem is described in the postgresql manual in the
backup section. Take a look at the manual too.
kind regards
