ST_IsValid is a relatively expensive operation, so be careful with that.
If you are using it a lot, it might be worthfile to just delete invalid
geometries once.
As it's the table used for the rendering deleting them might not be
possible.
I tried fixing them (only 3 left in Thailand) but for example relation
812277 seams to be fine.
The problem might be that an inner way shares a segment with the outer
way. Josm validater reports this as "intersection".
But that's the common way we're mapping it, right? I don't want to
duplicate the nodes.
