after vacuum analyze, explain still wrong

I ran vacuum analyze and immediately after I ran my query and the
estimated rows are way off. I suspect that it is something in my
configuration, but I don't know what.
I pasted my postgresql.conf file under the explain results.

Thank you
Sim

#
# This file consists of lines of the form:

#
# (The '=' is optional.) White space may be used. Comments are introduced
# with '#' anywhere on a line. The complete list of option names and
# allowed values can be found in the PostgreSQL documentation. The
# commented-out settings shown in this file represent the default values.
#
# Please note that re-commenting a setting is NOT sufficient to revert it
# to the default value, unless you restart the server.

# Any option can also be given as a command line switch to the server,
# e.g., 'postgres -c log_connections=on'. Some options can be changed at
# run-time with the 'SET' SQL command.

# This file is read on server startup and when the server receives a
