AppendStringInfoChar instead of appendStringInfoString

[Hou, Zhijie]

Hi

In (/src/backend/replication/backup_manifest.c)

I found the following code:

        appendStringInfoString(&buf, "\n");
        appendStringInfoString(&buf, "\"");

Since only one bit string is appended here, 
I think it will be better to call appendStringInfoChar.

Best reagrds,
