Get the total disk space used by a hypertable or continuous aggregate,
that is, the sum of the size for the table itself including chunks,
any indexes on the table, and any toast tables. The size is reported
in bytes. This is equivalent to computing the sum of
column from the output of
When a continuous aggregate name is provided, the function transparently looks up the backing hypertable and returns its statistics instead.

NULL is returned if the function is executed on a non-hypertable relation.
