I have postgresql running under FreeBSD on a small home server. I upgraded a number of ports, including postgres client and server, bringing postgres to v8.4.2.
Alas when I try to restart the database, I get an error message:
FATAL: unrecognized configuration parameter "max_fsm_pages"
I Googled this and it appear the following two lines in the configuration file are obsolete:
#max_fsm_pages = 20000 # min max_fsm_relations*16, 6 bytes each
#max_fsm_relations = 1000 # min 100, ~70 bytes each
So I deleted them, both from /etc/postgresql.conf
However, I still see the same error message when I try to restart postgres. Any idea what is going on here?
