I have 88,880 nr of posts under moderation. What should I do

I run this wordpress site at https://www.pakmusicblog.com

now i had it running for some months, and i had comments open for guests too. Now i did moderate the comments that ppl left, but i was away for some time and when i logged back into admin panel i saw the following:

# Awaiting Moderation (89630)

so i have 89630 nr of posts in moderation and ofcourse 99% of it is SPAM.

So whats the best way to delete all those 89630 posts? cuz i cannot do it via the webpage as it gets stuck loading those 89630 posts.

can i delete it from the sql? if yes which table do i empty.
