updates order of columns in compound PKs, update indexes e.g. we don't need a btree index on a column if it is the first column in the compound PK index but we do need a btree index for the later columns in a compound PK (searches on first column of a compound index are just as fast as searches on a btree index for that column alone, but searches on the 2nd or 3rd column in a compound index are significantly slower than on dedicated indexes)
