Uh, everything except the log_timezone setting.  I believe log files will
be named according to the local time in the log_timezone at the instant
they're created.

Did you set a max log of 2MB = 2097152 bytes ? Also, up to day 12, all logs roll at 19:00, perhaps to avoid the name collision with the second log file of day 13, it was saved as next available log name.

log_timezone is set to UTC, which is normally six hours ahead of 
Chicago, but does not observe DST, so currently it is five hours ahead. 
18:24 plus five is still the same day, 19:22 plus five is the next day.

Quoting the docs:

log_timezone (string)

Sets the time zone used for timestamps written in the server log. Unlike 
TimeZone, this value is cluster-wide, so that all sessions will report 
timestamps consistently. The built-in default is GMT, but that is 
typically overridden in postgresql.conf; initdb will install a setting 
there corresponding to its system environment.
