xmlserialize bug - extra empty row at the end

[Pavel Stehule]

Hi

maybe I found a bug in xmlserialize

SELECT xmlserialize(DOCUMENT '<foo><bar><val x="y">42</val></bar></foo>' AS
varchar INDENT);

(2023-04-23 07:27:53) postgres=# SELECT xmlserialize(DOCUMENT
'<foo><bar><val x="y">42</val></bar></foo>' AS varchar INDENT);
┌─────────────────────────┐
│      xmlserialize       │
╞═════════════════════════╡
│ <foo>                  ↵│
│   <bar>                ↵│
│     <val x="y">42</val>↵│
│   </bar>               ↵│
│ </foo>                 ↵│
│                         │
└─────────────────────────┘
(1 row)

Looks so there is an extra empty row.
