Re: [HACKERS] now about psql and one function

Why postgres should be using only for standard ways ?
I need to protect pg how its possible . Every single informacion which
user dont need to know he can not know . Each user is like enemy . :-)

I worry more about this cache , i dont know how to reset it.
Beca use i (in one transaction) make copy of table, drop it, create new
version and restore rows, but i can not do it because relcache remember
relid of this old table :( its any way to turn it off (for only replaceing
moment) or clien cache list  any idea ? (samole function is above)

PS.
Whato do you thing about \I in psql . Its will be like \i but befor
starting read file will be BEGIN; and if everythink will be ok will be
END; . ?
I know that i can do it manualy , but why i should do this when i have
soft as my help :

  ok, and this function :

  BEGIN
   CREATE TEMP TABLE ble (i INT);
   SELECT INTO cnt  count(*) FROM ble;
   DROP TABLE ble;

  and at first time everythink is ok, but in next time is error like this :
  pg_class_aclcheck : relation nr not found .
  (This function is only example , and i know that it doesnt sens)
  I think its by SysCache, how can i reset it ? or turn off ? or reload ?
