9.3.0? Really? There have been numerous and serious bugs fixed in the
9.3.x branch (I'm afraid it wasn't one of our most reliable releases).
I don't know offhand if any of them would explain this particular index
corruption, but you really need to be running something much newer.
9.3.15 is the current release in that branch.

Looks like severe corruption of an index. I do not think there's any
automated way to recover from this. If you don't want to revert to your
last backups (hopefully you have some) it's going to take manual forensic
analysis to see what can be extracted. There are various support
companies that specialize in Postgres data recovery ... it's unlikely
anyone will want to do it for free.
