I'm tempted to say we should do that in PostgresMain() instead, maybe
something like this:
diff --git a/src/backend/tcop/postgres.c b/src/backend/tcop/postgres.c
index 976a832..9e5557c 100644
--- a/src/backend/tcop/postgres.c
+++ b/src/backend/tcop/postgres.c
@@ -3769,6 +3769,8 @@ PostgresMain(int argc, char *argv[], const char *username)
MemoryContextSwitchTo(MessageContext);
MemoryContextResetAndDeleteChildren(MessageContext);
+ CHECK_FOR_INTERRUPTS();
+
initStringInfo(&input_message);
