Although, Debian code search [1] says this data structure is not used outside PostgreSQL, I wouldn't risk breaking third-party extensions during a minor upgrade (even if it is known that such data structure is from that particular output plugin -- pgoutput -- and other output plugins generally have its own data structure). +1 from Alvaro's proposal.
