New STATIC option for the cursor feature, 'STATIC' keyword. Mirrors
standard SQL definition of cursor behavior for STATIC option. This means
results fetched by the cursor will not reflect changes made to the data after
opening the cursor. Current implementation does not make a copy of the data,
but rather uses the ROW_TIMESTAMP pseudo column. As a result, to use the STATIC
option the target table must have designated a column as ROW_TIMESTAMP.
