There aren't very many link() calls in Postgres ... am I right to guess
that you're getting matching occurrences of this message in the
postmaster's log?

errmsg("could not link file \"%s\" to \"%s\" (initialization of log file %u, segment %u): %m",

A bit of googling suggests it's probably the same Ubuntu bug described
here:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/663069

According to that, you should be able to work around it by disabling
this rather-dubious-in-the-first-place security check.
