Hi, Aleksander, previous discussion was not a discussion actually, we proposed a set of big and complex core changes without any discussion preceding it. That was not very good approach although the overall idea behind the patch set is very progressive and is ready to solve some old and painful issues in Postgres.
Also, introduction of SQL/JSON will further boost usage of JSON in databases, so our improvements in JSON storage and performance would be very useful. These improvements depend on Pluggable TOAST, without API that allows easy plug-in different TOAST implementations they require heavy core modifications and are very unlikely to be accepted. Not to mention that such kind of changes require upgrades, restarts and so on. Pluggable TOAST allows using advanced storage techniques on top of the default Postgres database engine, instead of implementing the complex Pluggable Storage API, and allows plugging these advanced techniques on the fly - without even restarting the server, which is crucial for production systems. Discussion on extending the TOAST pointer showed some interest in this topic, so I hope this feature would draw some attention in the scope of widely used large JSON objects. -- Regards, Nikita Malakhov Postgres Professional The Russian Postgres Company https://postgrespro.ru/
