postgresql-docs-7.4.7-1.FC3.2 contains SGML sources of the docs, and some Makefiles that cannot be used to build the HTML docs. Shouldn't the HTML docs be shipped instead of the sources? Based on a very brief look, 8.0.1 in devel seems to be lacking the HTML docs as well, but it does not contain the SGML sources either.
The HTML docs reside in the base postgresql package. I agree that the SGML files are useless to the average user; they are removed as of the 8.0 packaging. *** This bug has been marked as a duplicate of 134450 ***
