Sorry, had the error message wrong:

ERROR:  cache lookup failed for relation 1906465919

It is on an exact table name.  When we retry the describe on a failure,
sometimes it works and sometimes it fails again.  When it fails again
the relation number is different. Also, \d schema.table always returns
quickly and never errors. \d table is slow and produces the error fairly
often.

They're using 8.0.x; I'm pretty certain it's 8.0.3.
