I'm cool with that.  It's possible that there are installations out
there that still have => operators installed, but every
still-supported release warns you not to do that, and the hstore
change exists in three released versions.  Anyway, no amount of
waiting will eliminate the hazard completely.

I think you should just remove the WARNING, not change it to an error.
If somebody wants to quote the operator name to be able to continue
using it, I think that's OK.
