Wouldn't that just be in cmdtaglist.h, but extended for nodes used for
replication commands? Then you could just call CreateCommandTag() to
get the command string to print as postgres.c does. There is already
one for repslot drop, in some way. This would have the advantage to
just call once set_ps_display() before the switch split.
