Agreed.=)

IIRC it closes file only on HUP or so, don't wanna to seek in sources.
So if you don't use syslog, place killall -HUP `tail -n1 /pidpath/postmaster.pid`
to postrotate clause and better use delaycompress if any.

Try this:
./configure blah-blah-blah --enable-syslog
make&&make install and so on
then
postgresql.conf:
# requires ENABLE_SYSLOG
syslog = 2 # range 0-2
syslog_facility = 'LOCAL2'
syslog_ident = 'postgres'
logrotate.d/postgres:
/path/postgres.log
{
daily
compress
delaycompress
rotate 10
notifempty
create 640 root postgres
}
syslogd.conf:
local2.* /path/postgres.log
