Docs build failure on plpgsql.sgml - Mailing list pgsql-docs

I am seeing a docs build failure :
openjade:plpgsql.sgml:1646:10:E: end tag for "SECT3" omitted, but
OMITTAG NO was specified
openjade:plpgsql.sgml:1640:5: start tag was here
make: *** [html] Error 1

Adding an extra </sect3> tag after line 1645 will make it build ok on my
system (not sure if that was the intent of the previous change tho)

regards

Mark
