Hi there,
I'm looking to use the PostgreSQL Hash Table for some custom functions.
However, the example, as per http://wiki.postgresql.org/wiki/HashTable crashes
postmaster (or segfaults from the cmd line) when trying to retrieve an element
from the hash.
Specifically this line fails: elem = ha
ation fault
Wondering if it was just me..?

Hi there,
I have some functions written in C that are dynamically loaded. I persist some
state between function calls, initialised by _PG_init. This works fine
I now fork() a process in _PG_Init() (both processes interact), but when I
shutdown postgre I get: LOG: failed to find proc 0x1331110
Thanks for your reply

Actually it's not doi

Thanks for that. The fork() is certainly more convenient than exec'g something
else - hopefully OK since we're just prototyping something.
Quick question: where is _exit_re
