I did a quick test, and found a problem. I shutdown the server, and “\c” reconnecting failed, but psql still show “read/write”, which seems wrong:

```
"read/write"\c
connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory
Is the server running locally and accepting connections on that socket?
Previous connection kept
hs=off ro=off
"read/write"
hs=off ro=off
"read/write"
hs=off ro=off
"read/write"
hs=off ro=off
"read/write”
```

Looks like I am too late to vote. Actually, if I had the chance, I would vote “rw/ro”.

And a question:
```
+ if (!hs || !ro)
+ strlcpy(buf, _("unknown"), sizeof(buf));
+ else if (strcmp(hs, "on") == 0 || strcmp(ro, "on") == 0)
+ strlcpy(buf, "read-only", sizeof(buf));
+ else
+ strlcpy(buf, "read/write", sizeof(buf));
```

Why wrap “unknown” in "_()” but not “read-only” and “read/write”?
