I made one significant change in the PL/Perl patch. You had this in
plperl_event_trigger_handler():
+ /*
+ * Create the call_data before connecting to SPI, so that it is not
+ * allocated in the SPI memory context
+ */
+ current_call_data = (plperl_call_data *) palloc0(sizeof(plperl_call_data));
+ current_call_data->fcinfo = fcinfo;
I think this is wrong, and the reason it crashes if you remove it is
that you need to call increment_prodesc_refcount(prodesc), like in the
other handlers.
Attached is my "final" patch. Let me know if it's OK for you.
