Hi,
pg_recvlogical continuously writes to the file specified with the --file option,
which means the output file can grow indefinitely. To manage file size,
some users may want to rotate the output periodically.
While reviewing the source code to find the way to rotate the file, I noticed
that pg_recvlogical reopens the output file when it receives a SIGHUP signal.
This makes file rotation possible: we can rename the current output file and
then send a SIGHUP to pg_recvlogical, which will close the renamed file and
open a new one with the same original name.
This is a useful feature, but it's currently undocumented. So I'd like to
apply the attached patch that adds this information to the documentation.
Thought?
Regards,
