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

You'll see it's linked against the sqlite client libraries too.
