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.
Build PostgreSQL from the sources. They are ahead in minor version number anyway.
