[Pgsql-ayuda] Rpm upgrade de 7.3.4 a 7.4

[Josué Maldonado]

Hola compañeros,

Tengo problema al intentar actualizar mi instalacion basada en RPMs de 
7.3.4 a 7.4, uso RH 8. En primera instancia obtuve este error:

/home/josue/pg74: rpm -Uvh *.rpm
error: Failed dependencies:
         perl(Pg) is needed by postgresql-contrib-7.4-0.2PGDG
         libpq.so.2 is needed by (installed) perl-DBD-Pg-1.13-5
         libpq.so.2 is needed by (installed) xemacs-21.4.8-16
         libpq.so.2 is needed by (installed) libdbi-dbd-pgsql-0.6.5-2
         libpq.so.2 is needed by (installed) mod_auth_pgsql-0.9.12-11
         libpq.so.2 is needed by (installed) qt-PostgreSQL-3.0.5-17
         libpq.so.2 is needed by (installed) php-pgsql-4.2.2-8.0.8
     Suggested resolutions:
         postgresql-perl-7.2.2-1.i386.rpm

Luego probe esta forma:
/home/josue/pg74: rpm -Uvh --nodeps *.rpm
Preparing...                ########################################### 
[100%]
         file /usr/include/sqltypes.h from install of 
postgresql-devel-7.4-0.2PGDG conflicts with file from package 
unixODBC-devel-2.2.2-3

Alguna idea o recomendacion, podria desinstalar por completo 7.3.4 y 
hacer una instalacion en limpio? si es si como lo desintalo? que 
diferencia hay en instalar de los fuentes o de los RPMs?

Gracias anticipadas,
