Well it's not only hstore. Anyone can CREATE OPERATOR => on any released
version of PostgreSQL currently. I don't think we can deprecate it on
short notice, so we'll have := in 9.0, and maybe a deprecation notice
for =>.
Now that it's pretty clear from Peter that the standard is not going to
change its choice here, I'll vote adding a WARNING each time an operator
called => is created, so that we get a chance to move later on.
