This is a very quick post that would hopefully save someone else hours of hitting the head on the wall like I did. If you are installing RedHat Enterprise Server 5.2/5.2 x86_64 on Dell PowerEdge server, be aware of the following issue with PostgreSQL binary installer offered by EnterpriseDB . After installation the server is unable to cleanly shutdown due to the fact that the binary installer does some voodoo with libtermcap - basically making this system library be used from inside postgres installation folder. Because of this, kernel can not umount / usr (or whenever your PostgreSQL is installed) and hangs the shutdown. Solution: Build PostgreSQL from the sources. They are ahead in minor version number anyway. Thanks.
