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 :>
