Re: hashtable issue - HASH_FIND??

Thanks for your reply.

Actually I had already changed the sizeof()s..

Not sure of the actual error, postmaster just dies:
NOTICE: Didn't find 9 -- good
NOTICE: about to extract object at key 0 (extra notice added by me)
LOG: server process (PID 55483) was terminated by signal 11: Segmentation fault

Wondering if it was just me..?

I think the "palloc(sizeof(key))" bits ought to be
"palloc(sizeof(*key))" ... or personally I'd have used
sizeof(HashKey). Although offhand it looks like that should
be the same size or larger, so it doesn't seem to explain a crash.
Where's the crash happening exactly?
