Oh, never mind me. I had assumed the SHMMIN mentioned in the postgresql
output would have a sysctl:

Sorry for the useless noise.

Ah, right. In that case, perhaps postgresql somehow allocates different
amounts of SHM based on some autodetection mechanism or other
circumstance, and lxc is somehow messing up this mechanism?

I'm just guessing here, perhaps someone with better lxc-fu has some more
useful contribution... :-)
