I found a rouge script in /etc/crontab.daily that ran the following line at 4:40am: /usr/local/pgsql/bin/pg_dump -h <domain name of localhost> -U tracking -cs | /usr/local/pgsql/bin/psql -U postgres tracking It must have been left over from before I got streaming replication up and working, when this box was still the backup server and not primary -i.e. the domain name in the first half wasn't for the local machine until I swapped machines. Apparently when you do a pg_dump with the -c flag from a server to itself, it does the clean before reading the data, resulting in a new empty database.
