Description:
------------
my name is mazdak.farrokhzad
i would like to request a mysql feature that would be mysql_db_size(),mysql_table_size(),mysql_column_size()
and mysql_row_size
what it would do is that it would get the lenght of a db,table,column and row
this would make the amounts of queries less
and this could be implemented for other databases too
if this is for plugin makers could you tell the please

Reproduce code:
---------------
here i am showing an example
mysql_connect('...','...','...');
mysql_select_db('...'); --> beacause db is selected you should not need to use the db parameters for table,column,row,size
let all functions accept float
and let them return true/false
echo mysql_db_size(mixed_var)/1024.'kb';
echo mysql_table_size(mixed_var)/1024.'kb';
echo mysql_column_size(mixed_var)/1024.'kb';
echo mysql_row_size(mixed_var)/1024.'kb';

Expected result:
----------------
depends on what you have in your code above
like
4kb
1.03715kb
0.005kb
0.000072436kb

Actual result:
--------------
look above
