I just noticed something: the "open files" limit lists 1024, which is the
default for this system. A quick count of open data files currently in use
by Postgres returns almost 7000, though.

[root(at)170226-db7 ~]# lsof -u postgres |egrep
'(/pg_data|/pg_index|/pg_log)' |wc -l
6749

We have 100+ postgres processes running, so for an individual process,
could the 1024 file limit be doing anything to this query? Or would I see
an explicit error message regarding this condition?
