One thing I was going to suggest is that pg_migrator check that all the
.so's in the old installation also exist in the new one. However that
could be overkill since you don't know for sure if the old .so is
referenced anywhere in the database.
As for the specific problem at hand, it might've been a mistake to
replace dblink_current_query() with a SQL function instead of changing
the internal implementation of the C function. We could still fix that.
