The bugs of libxml2 are unpleasant, on second hand, this library is fast
and almost time works well. One our benefit against other open source
databases is good XML support - and it cannot be replaced by JSON support.
Anybody who prefer absolute safety can use PostgreSQL without XML support.
We don't hide fact so we use libxml2, and anybody can check reputation of
libxml2
More - fresh libxml2 - 2.9.8 doesn't crash - so maybe this bug was fixed.
