Subject: pgsql: Fix low-probability memory leak in XMLSERIALIZE(... INDENT).
Date: Tue, 08 Jul 2025 16:50:47 +0000
Message-ID: <E1uZBWp-005Hyn-0g@gemulon.postgresql.org> (raw)
Fix low-probability memory leak in XMLSERIALIZE(... INDENT).
xmltotext_with_options() did not consider the possibility that
pg_xml_init() could fail --- most likely due to OOM. If that
happened, the already-parsed xmlDoc structure would be leaked.
Oversight in commit 483bdb2af.
Bug: #18981
