HI,
Consider the below test:
postgres(at)110311=#call sum(2+2);
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
Call stack:
(gdb) bt
#0 0x00007fef9b5851d7 in raise () from /lib64/libc.so.6
#1 0x00007fef9b5868c8 in abort () from /lib64/libc.so.6

proc_call=1 '\001',
location=5) at parse_func.c:726
Here it's hitting Assert() because pstate->p_expr_kind is set
to EXPR_KIND_NONE for the CallStmt function resolution.
Regards,
Thanks,
