Given n
input expressions, wraps them into n / width
rows, each of
width
columns.
This function is not intended to be called directly by end users, but is useful in the planning of e.g. VALUES clauses.
GenerateSubscriptsArray
TabletizedScalar
Execute some arbitrary scalar function as a table function.
