Note: When array binding is enabled (see ArrayBindCount property of the PsqlCommand Object), this property is specified as an array of values. Each array's length must match the value of the ArrayBindCount property. When specifying the array's values for binary type columns, the data will actually be specified as byte[]. This is an array of arrays of bytes. The data provider anticipates a "jagged" array as such when using parameter array binding with parameters.
