Here are my review comments for patch v17-0001.
======
src/test/regress/sql/xml.sql
The blank line(s) which previously separated the xmlserialize tests
from the xml IS [NOT] DOCUMENT tests are now missing...
e.g.
-- indent different encoding (returns UTF-8)
SELECT xmlserialize(DOCUMENT '<?xml version="1.0"
encoding="ISO-8859-1"?><foo><bar><val>42</val></bar></foo>' AS
text INDENT);
SELECT xmlserialize(CONTENT '<?xml version="1.0"
encoding="ISO-8859-1"?><foo><bar><val>42</val></bar></foo>' AS
text INDENT);
-- 'no indent' = not using 'no indent'
SELECT xmlserialize(DOCUMENT '<foo><bar><val
x="y">42</val></bar></foo>' AS text) = xmlserialize(DOCUMENT
'<foo><bar><val x="y">42</val></bar></foo>' AS text NO INDENT);
SELECT xmlserialize(CONTENT '<foo><bar><val
x="y">42</val></bar></foo>' AS text) = xmlserialize(CONTENT
'<foo><bar><val x="y">42</val></bar></foo>' AS text NO INDENT);
SELECT xml '<foo>bar</foo>' IS DOCUMENT;
SELECT xml '<foo>bar</foo><bar>foo</bar>' IS DOCUMENT;
SELECT xml '<abc/>' IS NOT DOCUMENT;
SELECT xml 'abc' IS NOT DOCUMENT;
SELECT '<>' IS NOT DOCUMENT;
~~
Apart from that, patch v17 LGTM.
