After I updated postgresql, a lot of my apps failed to run because they couldn't locate libpq.so. postfix is one of them. This problem is solved be re-emerging psotfix. The real issue is that since postfix depends on postgresql in my case, it should have been rebuild when i did emerge -uD world. Reproducible: Always Steps to Reproduce: 1. 2. 3.

No, it won
No, it won´t be rebuilt automatically (at least for now). We have revdep-rebuild for that. In this case, I´d suggest running `revdep-rebuild --soname libpq.so.3` to fix other packages that depend on postgresql libraries.
