Disabling libpq clients stderr output from backend

Hello,

I have a client C++ program that is built on top of libpq. Whenever I issue
an SQL query that executes a stored procedure that drops tables or creates
tables, I get the NOTICE: messages to appear on the stderr output of my
client propram. Can I turn this off, or redirect it to /dev/null somehow?
