That is highly suspicious.

What do you get if you run

SHOW segment_size;

Unless you built PostgreSQL yourself after changing the segment size,
it should be 1GB. But then it would be impossible for some segment
to be bigger than 1GB.

Are you using some weird file system that reports file sizes wrongly?

What does "ls -l" on one of these big files show?
