no Update available Postgresql 9.3 RHEL5 X86_64

Dear PostgreSQL RPM Building Project,

ist there a Problem with updating in this combination
(RHEL5 X86_64, PostgreSQL 9.3)?

On our CentOS-Boxes, 9.3.7 is available,
on our RHEL5-Boxes it is not.

Maybe it's my fault, but I don't remember changing anything.

VlG
