So how does one go about using a table name from
information_schema.tables in pg_table_size()?
Find that the function signature in the documentation requires an input
of "regclass" and ignore attempts to pass anything but that to the function.
pg_table_size ( regclass ) → bigint
I observe in v13 that the expected syntax works just fine:
select pg_table_size((table_schema || '.' || table_name)::regclass) from
information_schema.tables;
Yeah I tried that, didn't include in my previous post:
select pg_table_size((table_schema || '.' || table_name)::regclass) from
information_schema.tables;
