Not really. You could either interpolate @extschema@ into the text
of the referencing function, or (though much inferior for performance)
have it SET SEARCH_PATH FROM CURRENT. Either of those changes would
involve an extension version bump since they're changing the extension
script. What's more of a problem is that we could no longer claim
the extension is relocatable. My unaccent fix dodged that by looking
up the C function's current schema, but I don't think there's any
equivalent functionality available at SQL level.
