Hi,
Is possible the limit the size of an user (quota user) as space
allocated in a tablespace ?
I don't find this option in the 9.0 version of PG,
so I think it is not available.
Perhaps it should be possible to simulate it using triggers.
However before start to work on it , I like to have a confirm and if
there is some documentation or information on this
problem available.
what exactly would this limit?
The total size of tables created by that user regardless of what role
inserted data into said tables? There's really no way to track the
data written by a user into tables that multiple users have
insert/update privs to. and does it include older tuple versions
that aren't yet vacuumed?
calculating pg_total_relation_size is fairly expensive, too, it requires
scanning the table and ancilliary items (indexes, toast storage) to sum
up the number of blocks allocated.
