it will not break anything because you can set this flag in the
VERSION/PLATFORM COMPATIBILITY section of postgresql.conf

[SQL] delete from a using b in postgres 8.1.

[Peter Childs]

a command such as

delete from a using b where a. and b.two='foo';

works fine in 8.1 but fails totally in 8.0 however

delete from a where a. and b.two='foo';

works fine in 8.0 and bellow but fails in 8.1 unless you have the add_missing_from option set to true in 8.1 
Even then it produces a nasty warning.

This can break tones of clients admittedly the work around is quick but
not particularly neat. What do the other sql database do and is this
just another inconstancy in SQL?

I realise this was done to fix a bug but its a nasty sitting there that
many client developers are going to miss it before it goes back to the
end user. I also don't think  this has been made particularly
clear in changes.
