logs. I think this does some neat tying together of how to use FDWs that the docs are currently lacking. 

Interesting ...

The final query is a bit unwieldy.  I wonder if this would work

CREATE TABLE generic_pglog (
  log_time timestamp(3) with time zone,
  user_name text,
  database_name text,
  process_id integer,
  connection_from text,
  session_id text,
  session_line_num bigint,
  command_tag text,
  session_start_time timestamp with time zone,
  virtual_transaction_id text,
  transaction_id bigint,
  error_severity text,
  sql_state_code text,
  message text,
  detail text,
  hint text,
  internal_query text,
  internal_query_pos integer,
  context text,
  query text,
  query_pos integer,
  location text,
  application_name text
);

CREATE FOREIGN TABLE pglog (LIKE generic_pglog) SERVER pglog
OPTIONS ( filename '/home/josh/9.1/data/pg_log/pglog.csv', format 'csv' );

Note that you have a "Not" instead of "now" in the last paragraph.
