How can I increase the stack depth limit ? Is it only by modifying the postgres.conf file, but there I cannot increase the stack depth beyond 4 MB. Actually, my problem is that, when I set the stack base address of the child thread using the POSIX library function "pthread_setstackaddr()", I am unable to access the memory contents of its parent. The data-structures in the parent are either getting destroyed or unaccessible when moving to the context of the child thread.
It is not a good idea to use threads in server code. PostgreSQL server code is not thread-safe, things will break.
Assuming that you're not actually doing that but using threads in the client instead, max_stack_depth should have no effect on you as it only affects the server.
But you really should find another way to communicate between threads. Stacks should be treated as thread-private. Use malloc() or something and global variables.
