RPM (YUM) dependency question

[John Wendel]

I recently wanted to rebuild Postgres from sources on my play box. I 
thought I'd start by removing the existing Postgres installation and 
ran into what seems to be a strange dependency. For some reason, 
Apache depends on postgres-libs. Can someone explain why this is required?

Thanks,

John
