Hi, Sometimes I set RELSEG_SIZE to 1, as a way to get the various in-tree tests to give the relation segment code a good workout. That's outside the range that configure --with-segsize would allow and therefore not really a supported size (it's set in GB), but it's very useful for giving the relation segment code a good workout on small databases like the check-world ones. At some point I think that worked, but now it says:
t/010_pg_basebackup.pl ... 100/106 # Failed test 'pg_basebackup does not report more than 5 checksum mismatches stderr /(?^s:^WARNING.*further.*failures.*will.not.be.reported)/' # at t/010_pg_basebackup.pl line 526. # 'WARNING: checksum verification failed in file "./base/13759/16396", block 0: calculated 49B8 but expected A91E # WARNING: could not verify checksum in file "./base/13759/16396", block 4: read buffer size 8225 and page size 8192 differ # pg_basebackup: error: checksum error occurred # ' # doesn't match '(?^s:^WARNING.*further.*failures.*will.not.be.reported)' I haven't quite figured out why it does that yet (I don't see any files of size other than 0 or 8192, as expected), but it'd be nice to do that. I was even thinking of running a bf animal that way.
