hi i need to know all the database overhead sizes and block header sizes etc etc as I have a very complex database to build and it needs to be speed tuned beyond reckoning I have gathered some relevant information form the documentation such as all the data type sizes and the RM block information but I don't have any information on INDEX blocks or other general overheads http://www.peg.com/techpapers/monographs/space/space.html http://www.postgresql.org/docs/8.1/static/datatype.html I am using postgres 8.1 if anyone can post links to pages containing over head information and index block header information it would be most appreciated as I cannot seem to find anything Regards Kelvan ---------------------------(end of broadcast)--------------------------- TIP 7: You can help support the PostgreSQL project by donating at http://www.postgresql.org/about/donate
