I have used sigprocmask() to block the reception of certain signals
26-
while the program is executing SQL queries. This prevents a user
27-
pressing Control-C from stopping all the back ends. It blocks SIGHUP,
28-
SIGINT, and SIGTERM, but does not block SIGQUIT or obviously kill -9.

If your platform does not support sigprocmask(), you can remove those
30-
function calls. ( Am I correct that abnormal termination can cause
31-
shared memory resynchronization?)

There is a demo program called pginsert that demonstrates how the
3426
library can be used.
