Re: [Pljava-dev] stack depth limit exceeded - patch possible?

Dear Kris,

am I understanding this correctly that pl/java sets it for the main Java
thread, so other threads spawned by this main thread and using postgres
SPI functionality will run into stack_depth_problems?

I have read only access in this application, so maybe my envisioned
patched version (check_stack_depth doing nothing) will work for my proof
of concept tests.

Can you suggest another workaround?

Regards,

Alexander Wöhrer
