Since you are not splitting an array but returning an array, I would think that "regexp_split_to_array" would be better, and the other should then be "regexp_split_to_table". But why does the second one have a limit and the first one doesn't? Is this because you rely on the LIMIT clause to do the same? Is there a guarantee that LIMIT on a table function makes a consistent order? -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
