One of the nasty features of TAR format is that it needs to know the file
size before adding it to the archive. As a result, pg_dump stores the file
in the /tmp directory before moving it to the actual output file. For huge
files, this means /tmp must be able to cope with the uncompressed size of
the largest table. It's horrible, I know, which is why I use -Fc, but I'd
guess this is the cause of your error.
It uses tmpfile() to get a temp file, so I can't see a simple way to test
this, unless you can free up 2+GB in /tmp?
Please let me know if this is the cause, and if you can not test it, I will
try to send a patch to (temporarily) avoid using tmpfile(). Ideally, I
suppose pg_dump should support the ability to override the tmpfile() location.
Bye for now,
Philip
