If this question is answered in some FAQ, I'd be happy just for some
pointer. If not, what I'd like to know is this: Since I will be using
PostgreSQL (because it's the database I know best and because I like it ;))
for a content management type app where I need TOAST, I am wondering whether
this mechanism is actually something really advanced and neat (this is what
I'd assume) or if it is a not-so-elegant, rather involved construction to
get around a legacy limitation? To put it another way: Can I go around
bragging to my SQL-minded friends about using this really cool thing that no
other database has, or should I keep my mouth shut because it's actually not
so cool? How do the MySQL people do it (there's a pretty instructive
comparison of MySQL and PostgreSQL at
http://www.phpbuilder.com/columns/tim20000705.php3 in the context of both
databases' suitability as a web site backend which mentions the 8k barrier
as one of the bigger minuses of PostgreSQL - it's a head-to-head race in
this comparison by the way, which makes it particularly interesting)? What's
Oracle's answer to oversized attributes (or other advanced DBMS's, like
Sybase, Informix et al)?

Thanks, Frank
