Hello!
Path is ignored with a positional argument, I think this is a bug?
This fails:
pg_waldump --path /wal/dir 000000010000000000000001
And this works:
pg_waldump --path /wal/dir --start 0/01000028 --end 0/010020F8
+{
+ int fname_len = strlen(fname);
+
Shouldn't this use size_t?
+ /*
+ * Setup temporary directory to store WAL segments and set up an exit
+ * callback to remove it upon completion.
+ */
+ setup_tmpwal_dir(waldir);
Maybe this could be deferred to be created only on first use? If I
understand correctly, in a typical scenario waldump won't use this
temporary directory, yet it always creates it.
