The release notes of upgrades usually indicate whether initdb is required or not. Generally when the last digit of a version change it does not require a dump and reload. In this case the release notes say:
http://www.postgresql.org/docs/7.4/static/release.html#RELEASE-7-4-5
E.1.1. Migration to version 7.4.5
A dump/restore is not required for those running 7.4.X

Will a DB created under 7.4.2 work with 7.4.5, or do I need to back it up and restore it to a newly created 7.5.4 DB?
