[CentOS] RPM conflicts - help!

[Benjamin Smith]

Well, in this case, I've long been aware of the dump/reload cycle when 
incrementing any major version, and had already setup PG 8.1 using the RPMs 
from the PostgreSQL website, so for me, it was just a case of removing the PG 
RPMs and then installing the CentOS RPMs. 

Where this broke is that php-pgsql was looking for libpg.so.3, but PG 8.1 
installs libpg.so.4, and AFAI can tell, this is now resolved.
