"catalog change": CREATE or ALTER a pg_* table. "on-disk structure", a.k.a. "user table format": the way that the tables/fields are actually stored on disk. So, a catalog change should *not* require a dump/restore, but an ODS/UTF change should. Agreed? -- ----------------------------------------------------------------- Ron Johnson, Jr. ron.l.johnson@cox.net Jefferson, LA USA "they love our milk and honey, but preach about another way of living" Merle Haggard, "The Fighting Side Of Me"
