Ok, I'm glad.
I installed another version of postgresql (8.1) because of timezone is not working on my old installation (postgre 7.4).
After postgresql installed, I run the alfresco but it doesn't work.
The alf_data and database was created, but the caches.xml files was not.
It is happen some errors (I deleted the two files cache, alf_data and data_base):

Is there some imcompatibility between postgresql version 7xx and 8xx, related with functions?? what next? what about the caches files?
