• RENAME TO clause to rename the continuous aggregate view
• RENAME [COLUMN] clause to rename the continuous aggregate column

• SET TABLESPACE clause to move the materialization of the continuous aggregate view to the new tablespace
• OWNER TO clause to set new owner for the continuous aggregate view

ALTER MATERIALIZED VIEW <view_name> SET ( timescaledb.<option> =  <value> [, ... ] )

To disable real-time aggregates for a continuous aggregate:

ALTER MATERIALIZED VIEW contagg_view SET (timescaledb.materialized_only = true);

Copy

To enable compression for a continuous aggregate:

ALTER MATERIALIZED VIEW contagg_view SET (timescaledb.compress = true);
