Hmm, isn't project style more usually to include the error reason
in the primary message? That is,

ereport(LOG,
- (errmsg("could not drop the replication slot \"%s\" on publisher",
- slotname),
- errdetail("The error was: %s", res->err)));
+ (errmsg("could not drop the replication slot \"%s\" on publisher: %s",
+ slotname, res->err)));

and so on. If we had reason to think that res->err would be extremely
long, maybe pushing it to errdetail would be sensible, but I'm not
seeing that that is likely.

(I think the "the" before "replication slot" could go away, too.)
