I know from firsthand experience that there were investment banks doing this at least as early as the mid 1990s - on top of Sybase in the particular case I have in mind. Perhaps not the best performance, but it was trivially easy to inspect, and you could integrate with other database features, for example stored procedures.
Back when I worked for France Telecom circa 1996–99, Sybase Replication Server was the fastest message queue we tested for transporting billing events, by a wide margin, in a way that predated Postgres logical replication by 3 decades.
