Ok I understand now that this row(t.*) syntax is new to postgres 8.2
As explained in the documentation, §4.2.11. Row Constructors:
A row constructor can include the syntax rowvalue.*, which will be expanded to a list of the elements of the row value,
justas occurs when the .* syntax is used at the top level of a SELECT list. For example, if table t has columns f1 and
f2,these are the same:
SELECT ROW(t.*, 42) FROM t;
SELECT ROW(t.f1, t.f2, 42) FROM t;
This would obviously simplify the syntax of my queries a lot since I have so many columns. I'm going to try and
installthe newest version and check it. I'll keep you informed.
Thanks to all!

Don't forget to reply all so that everyone on the list can participate. Also, do this is good since it doesn't limit
youto my limited knowledge. ;)
row() doesn't do what you think it does.
you have to specify every column that you want to compare, so:
row(t.col1, t.col2, t.col3, t.col4) <> row(p.col1, p.col2, p.col3, p.col4)
where the datatypes of each respective column match. i.e. t.col1 maps to p.col1, ...
