Re: Introduce XID age and inactive timeout based replication slot invalidation

Hi Nisha, here are my review comments for the patch v51-0001.

======
src/backend/replication/slot.c

ReplicationSlotAcquire:

1.
+ ereport(ERROR,
+ errcode(ERRCODE_OBJECT_NOT_IN_PREREQUISITE_STATE),
+ errmsg("can no longer get changes from replication slot \"%s\"",
+    NameStr(s->data.name)),
+ errdetail_internal("%s", err_detail.data));
+
+ pfree(err_detail.data);
+ }
+

Won't the 'pfree' be unreachable due to the prior ereport ERROR?

Kind Regards,
