With namespace support, is all data still stored in the same physical table for all views, even if the views have different schemas? For example, given the following: CREATE VIEW s1.a AS SELECT * FROM t WHERE k=1; CREATE VIEW s2.b AS SELECT * FROM t WHERE k=2; CREATE VIEW s3.c AS SELECT * FROM t WHERE k=3; Would the following query still return all rows across all three views?
