Yeah --- in a normal installation, initdb will provide un-commented
entries for these postgresql.conf parameters:

max_connections
shared_buffers
max_fsm_pages
datestyle
lc_messages
lc_monetary
lc_numeric
lc_time

(The first three are set dependent on SHMMAX probing, the others
dependent on locale.)  Your conf file doesn't seem to have been through
that autoconfiguration step, which suggests someone poking at things
they should have left alone.
