It seems to me that it should be possible to create a language front end for Andl by creating a background worker and a language handler. The BGW will need to implement the Andl language and a listener, and submit generated SQL to SPI. The PL will get called by query functions and pass them to the BGW (via a callback) for execution. AFAIK the BGW and the PL run in the same process, and this should work. Apart from reading the documentation (I have), reading source code (worker_spi.c) and heeding warnings about the risk of breaking the server, is there any reason why this would not work? There is a fair bit of work, and it would be nice to know what to watch out for.
