That's not too surprising because I don't believe there are any
CHECK_FOR_INTERRUPTS calls in the basic lex/parse loop. That wouldn't
normally be a problem because that phase is pretty quick, but it is a
problem if the system is spitting tons of messages at you.

It seems like a reasonable thing to do would be to add a
CHECK_FOR_INTERRUPTS in elog.c just after sending a notice/warning
message to the client.

Comments?
