How to Delete Existing WordPress Post Revisions Stored/Saved
For users who had disabled or turned off post revisions tracking or versions history feature in WordPress (added since WordPress 2.6), it is also made sense to delete and remove all existing stored post revisions and changes made on pages stored in the database in order to reduce the wp_posts table size, especially when there is already tons of revisions or changes been kept.
To delete and remove all existing post revisions entries and rows from WordPress database Posts table, simply login to MySQL command-line interface, phpMyAdmin, SQLyog or other MySQL GUI tools. Select the appropriate WordPress database (if you have more than one databases on the same server), and then issue the following command (it’s also recommended to backup the database before performing the deletion SQL statements):
DELETE FROM wp_posts WHERE post_type = "revision";
Once all post revisions related records is purged, all revision histories is deleted, and users no longer able to check the changes by phase or compare differences between versions. Thus, deletion may also been used by administrator to ensure privacy or stop authors or writers in the blog from knowing their posts have been edited.

I just tried this and it worked, great. Thank you. I have so many revisions it gives me a headache to look at the list on the page. And then to know that my database is storing all of that.
I’m on Bluehost and at first couldn’t figure out where to place the command script line. So I had to experiment and here’s what I did:
On my database page, the 2nd tab is called “SQL’. There is a field there called “Run SQL query/queries on database”. You paste the line of code in there, click “GO” and presto.
You get to start all over with the new revisions.

Here’s an easier way – add
define(‘WP_POST_REVISIONS’,6);
to your wp-config.php file. change the 6 to however many revisions you want or -1 to keep them all. Wordpress will delete the surplus revisions next time you save the post / page.

Great Guide!!!
Seriously, I have one blog that is over 2 years old, that blog has seen more than it’s fair share of revisions and updates, thus the revision history was pretty clogged up. I turned this feature off, but didn’t know how to delete the history, which mean’t the mysql database was horrible!
I only noticed as I forgot my password recently (ooops!) and had to pop into phpmyadmin to reset it, whilst there, well, lets just say I am going to print off your instructions, and clear the mess up a bit! – Nice one, thanks so much for the tips!!!
JOhn.

Salut,
Ce n’est pas suffisant, il y a deux autres tables affectees par l’autosave (wp_term_relationships et wp_postmeta), le code complet serait:
delete x,y,z
from wp_posts x
left join wp_term_relationships y on (x.id = y.object_id)
left join wp_postmeta z on (x.id = z.post_id)
where x.post_type = 'revision'

I don’t need the post revision feature either, as I’m the only author of my blog. Thanks for this tip.

Great tip!
The revisions take up a huge amount of space when editing posts.
I installed a new skin and had to edit each post to match….. twice the database size
Thanks for this tip, very useful!
