sql - Grant an automatic select to a all tables / PostgreSQL -


i have production database, user can create set of tables inherits master table x. matter when want apply automatic grant tables;

naturally command : grant select on tables in schema public read_only ; applied tables have been created.

the aim, applied command newest tables.

nb : tried make trigger on tables pg_class, pg_namespace it's impossible , it's same pg_tables view;

you can set default grants newly created objects alter default privileges command, e.g.:

alter default privileges user creator_role in schema public grant select on tables read_only;

as aside, while can't install triggers on system catalogs, can achieve same thing (in postgres 9.3+) event triggers, fire on create/drop/alter statement.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
