Hi, pg_waldump options, --follow or -f(to keep polling once per second for new WAL to appear) and --stats or -z don't work well together i.e. the command stucks [1]. I think the pg_waldump should emit an error. Note that the pg_basebakup does error out on incompatible options.
Here's a small patch for fixing above along with a note in the documentation. Thoughts? [1] The following commands stuck: ./pg_waldump -p data/ -s 0/7000060 -f -z ./pg_waldump -p data/ -s 0/7000060 -f --stats='record' ./pg_waldump -p data/ -s 0/7000060 -f --stats='rmgr' [2] ubuntu3:~/postgres/inst/bin$ ./pg_waldump -p data/ -s 0/7000060 -f -z pg_waldump: error: --follow and --stats are incompatible options Try "pg_waldump --help" for more information. bharath@bharathubuntu3:~/postgres/inst/bin$ Regards, Bharath Rupireddy.
