Hi All,

Is there a way to limit user's CPU resource specially on "SELECT" query ?

I hava a table with a lot of rows inside, if one sloopy DB users do a
"SELECT * FROM bigtable"
then CPU resource will go near 99% and this action will surely affect
the other database performance ...

Thanks.

TIP 9: In versions below 8.0, the planner will ignore your desire to
       choose an index scan if your joining column's datatypes do not
       match
