OK, I don't understand this. attalign is 'd', which is already the maximum possible, and even if it weren't, individual rows can't decide to use a larger OR smaller alignment than expected without breaking stuff. In what context is it OK to just add extra alignment padding? -- Robert Haas EDB: http://www.enterprisedb.com
