Great. I'm checking this patch and it seems, indentation stops working if
we have a text node inside:

gitpod=# select xmlserialize(document '<xml><more>13</more></xml>' as text
indent);
              xmlserialize
----------------------------------------
 <?xml version="1.0" encoding="UTF-8"?>+
 <xml>                                 +
   <more>13</more>                     +
 </xml>                                +

(1 row)

gitpod=# select xmlserialize(document '<xml>text<more>13</more></xml>' as
text indent);
              xmlserialize
----------------------------------------
 <?xml version="1.0" encoding="UTF-8"?>+
 <xml>text<more>13</more></xml>        +

(1 row)

Worth to mention, Oracle behaves similarly -- indentation doesn't work:

But is this as expected? Shouldn't it be like this:
<xml>
  text
  <more>13</more>
</xml>
?
