Carol,

Do the following in psql:

show config_file;

You should get some output like so:

config_file
-------------------------------------
/var/lib/pgsql/data/postgresql.conf
(1 row)

Go forth and edit that file. :-)

I'm not sure I understand the question. max_fsm_pages is the maximum
number of pages to be used in the free space map. See Jim Nasby's
article here: http://decibel.org/~decibel/pervasive/fsm.html

What's the error? All I see in this email is a warning about
max_fsm_pages and that should not stop you from doing a pg_dump.
