Yup, in SQL200x at least:
14.9 <merge statement>
Function Conditionally update rows of a table, or insert new rows into a table, or both.
Format <merge statement> ::= MERGE INTO <target table> [ [ AS ] <merge correlation name> ] USING <table
reference> ON <search condition> <merge operation specification>
At the risk of stirring up a debate again, my latest thoughts were to
define the two functions as:
str_to_array(str TEXT, delim TEXT) returns TEXT[] array_to_str(array ANYARRAY, delim TEXT) returns TEXT
