As suggested by Peter and Nikolay, v15 now removes the xmlformat

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: https://dbfiddle.uk/hRz5sXdM.

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