I found on http://www.madeasy.de/7/ext2.htm (in german) ext2 can't have bigger files than 16GB if blocksize is 1k. Ext3 is ext2 with journaling.

Hello
We are having problems with pg_dump.
We are trying to dump a 30GB+ database using pg_dump with the --file option. In the beginning everything works fine, pg_dump runs and we get a dumpfile. But when this file becomes 16GB it disappears from the filesystem, pg_dump continues working without giving an error until it finnish (even when the file does not exist)(The filesystem has free space).
I can generate without problems files bigger than 16GB with other
programs.

Any ideas? It looks like pg_dump has a limit of 16GB? How can we solve this?
