    Multiple security issues were discovered in PostgreSQL, which may     result in execution of arbitrary code, incorrect authentication,     information disclosure, or privilege escalation.

    The upstream fix to address CVE-2026-6471 requires additional changes     to the configuration if some extensions are used. This affects the     postgresql-17-wal2json, postgresql-17-squeeze, postgresql-17-pg-rewrite     and postgresql-17-decoderbufs extensions included in Debian.
    Quoting from the changelog:

    | Restrict logical decoding output plugins to the set specified by     | a new server parameter `output_plugin_libraries` (Jacob     | Champion)     | Previously, a replication user could select any loadable library     |     | Restrict logical decoding output plugins to the set specified by     | a new server parameter `output_plugin_libraries` (Jacob     | Champion)     | Previously, a replication user could select any loadable library     | for logical decoding, allowing exploits of various sorts. To     | allow locking this down without breaking setups that worked     | before, introduce a whitelist of allowed output plugins.
    |     | By default, only the output plugins shipped as part of     | PostgreSQL (`pgoutput` and `test_decoding`) are included in     |`output_plugin_libraries`. Installations that rely on other     | output plugins must add them after updating the server, for     | example     |     | output_plugin_libraries = 'pgoutput, test_decoding, my_trusted_decoder'

    For the stable distribution (trixie), these problems have been fixed in     version 17.11-0+deb13u1.

    We recommend that you upgrade your postgresql-17 packages.
