And in fact a bit of experimentation proves that it doesn't, unless
there are uncommented log_rotation_age and log_rotation_size entries
in postgresql.conf. So this is a bug, not to mention bad practice.
I think the code needs to use an explicit "rotation_disabled" flag
that it can reset in the SIGHUP block, instead of stomping on GUC
variables.
However, it remains far from clear whether this has anything to do with
Josh's situation. If it does, there should be telltale messages in
his log ...
