Re: add log messages when replication slots become active and inactive (was Re: Is it worth adding ReplicationSlot active_pid to ReplicationSlotPersistentData?)

Some minor comments for v17-0001.

======

1.
+       ereport(log_replication_commands ? LOG : DEBUG1,
+               SlotIsLogical(s)
+       /* translator: %s is name of the replication slot */
+               ? errmsg("acquired logical replication slot \"%s\"",
+                        NameStr(s->data.name))
+               : errmsg("acquired physical replication slot \"%s\"",
+                        NameStr(s->data.name)));

1a.
FWIW, if the ternary was inside the errmsg, there would be less code
duplication.

1b.
I searched HEAD code and did not find any "translator:" comments for
just ordinary slot name substitutions like these; AFAICT that comment
is not necessary anymore.

SUGGESTION (#1a and #1b)

ereport(log_replication_commands ? LOG : DEBUG1,
        errmsg(SlotIsLogical(s)
               ? "acquired logical replication slot \"%s\""
               : "acquired physical replication slot \"%s\"",
               NameStr(s->data.name)));

2.
Ditto for the other ereport.
