Not really there was a regression with squashfs+overlayfs but it is
fixed in 4.13.4.
(fix false positive ESTALE on lookup)
I tries mounting squashfs+overlayfs to /var/lib/postgresql and create
db on Ubuntu
and it seemed ok.

- strace of the failing postgresql db create
- dmesg from that time, specifically "overlayfs" messages
- output of cat /proc/self/mountinfo (or better postgres pid instead of self)
