Hello everyone,

I'm building In-Memory index extension for Postgres, for which i'm trying to use DSA. But ended with some issues, as it is not allowing me to create DSA(Dynamic Shared Area) in _PG_init function.

Please refer my_PG_init code below:
void
_PG_init(void)
{
area = dsa_create(LWLockNewTrancheId(), "CustomIndex_DSA");
area_handle = dsa_get_handle(area);
}


Because of this code, Postgres is not starting. Not even giving any error messages in pg logs. Hence, i'm totally clue less :(


Please let me know how to proceed. Your help is highly appreciated.


PS: Applied all the DSM related patches over Postgres 9.6.1 as per below thread and confirmed the same by running some test programs.

Thanks & Best Regards,
