Well you assign a value to a named parameter, so I don't see the point.
Now SELECT myfunc(a := 1, b => 2); is about fine, the only point is that
the => operator looks good for associative things such as hstore, so
chances that it has been used are not so low.
I guess we could choose to go with := for 9.1 and revisit the =>
situation after the SQL standard has settled on the new version. Maybe
this move would even have some impact now that we have a voice over
there.
