archive_command does not execute

Hi,

I am attempting to use the WAL archiving on a Solaris machine, running
PostgreSQL 8.1.4. The archive_command specified in the postgresql.conf file
does not get executed, nor do I see any log entries showing errors etc.
What am I doing wrong here?

Here is the relevant fragment of my conf file:

fsync = on # turns forced synchronization on or
off

wal_sync_method = fsync # the default is the first option

# supported by the operating system:

# open_datasync

# fdatasync

# fsync

# fsync_writethrough

# open_sync

#full_page_writes = on # recover from partial page writes

#wal_buffers = 8 # min 4, 8KB each

#commit_delay = 0 # range 0-100000, in microseconds

#commit_siblings = 5 # range 1-1000

# - Checkpoints -

checkpoint_segments = 1 # in logfile segments, min 1, 16MB each

checkpoint_timeout = 30 # range 30-3600, in second

checkpoint_warning = 5 # in seconds, 0 is off

# - Archiving -

archive_command = 'touch /var/lib/pgsql/bkp/myfile'

Here is my log entry for the duration of the test:

FATAL: terminating connection due to administrator command

LOG: shutting down

LOG: database system is shut down

Thanks in advance,
