Hi,
ISTM that pg_rewind's --source-pgdata and --source-server options are
mutually exclusive, and the synopsis in the documentation seems to
indicate that as well:
|pg_rewind [option...] {-D | --target-pgdata} directory
|{--source-pgdata=directory | --source-server=connstr}
However, there is no such check in the code.
I've seen people assume --source-pgdata is supposed to be the data
directory location on the remote server if they specify --source-server
as well, and are then confused by error messages.
So I think pg_rewind should abort in this case. Patch for that attached.
Thoughts?
Michael
