Some more feedback:
1. There's a typo in line 578 which makes it fail to compile:
|src/bin/pg_checksums/pg_checksums.c:578:4: error: ‘y’ undeclared (first use in this function)
| }y
2. Should the pqsignal() stuff only be setup in PG_MODE_ENABLE? Same
with the controlfile_path?
3. There's (I think) leftover debug output in the following places:
|+ printf(_("Renaming \"%s\" to \"%s\"\n"), controlfile_path,
|+ controlfile_path_temp);
|+ printf(_("Renaming \"%s\" to \"%s\"\n"), controlfile_path_temp,
|+ controlfile_path);
|+ printf(_("Syncing data folder\n"));
(that one is debatable, we are mentioning this only in verbose mode in
pg_basebackup but pg_checksums is more chatty anyway, so probably fine).
|+ printf(_("Updating control file\n"));
Besides to the syncing message (which is user-relevant cause they might
wonder what is taking so long), the others seem to be implementation
details we don't need to tell the user about.
