The following bug has been logged on the website:
Bug reference: 12469
Logged by: Karl O. Pinc

PostgreSQL version: 9.1.14
Operating system: LInux, Scientific Linux 6.5 (a RH clone)
Description:
Hi,
Sorry, I've no idea if I can repdoduce this bug. Thought it better to
report it as it is happening.
I found that after running a large transaction (for days, it's still
running) and then running out of shared memory that pg_locks reports locks
held by pids that do not seem to exist, either in ps output or in
pg_stat_activity. There are continued reports of running out of shared
memory.

This large transaction is attempting to load 727,163,525 bytes of text (a
VCF file) by parsing and inserting (using INSERT, via sqlalchemy) into about
10 tables, selecting from the 10 tables and 3 others for a total of 13
tables.

# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
# name = value
#
# (The "=" is optional.) Whitespace may be used. Comments are introduced
with
# "#" anywhere on a line. The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default
values.
# Re-commenting a setting is NOT sufficient to revert it to the default
value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal. If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload". Some
# parameters, which are marked below, require a server shutdown and restart
to
# take effect.
#
# Any parameter can also be given as a command-line option to the server,
e.g.,
# "postgres -c log_connections=on". Some parameters can be changed at run
time
# with the "SET" SQL command.
#
# Memory units: kB = kilobytes Time units: ms = milliseconds
# MB = megabytes s = seconds
# GB = gigabytes min = minutes
# h = hours
# d = days

# option or PGDATA environment variable, represented here as ConfigDir.
