[GENERAL] Again about varchar()

[李彦 Ian Li]

Hi all:

I have tables with one or several varchar(n) columns(utf8, n<=200) 
which I believe those tables' row length will not exceed the page 
length. Will it helps to the performance that I turn off TOAST of 
those 'short' varchar() columns by issuing “ALTER TABLE foo ALTER 
COLUMN bar SET STORAGE PLAIN”?

Regards
Ian
