make installcheck # shut down postgres with Ctrl-C pg_verify_checksums data pg_verify_checksums: checksum verification failed in file "data/base/16384/28647", block 65: calculated checksum DC70 but expected 0 pg_verify_checksums: checksum verification failed in file "data/base/16384/28649", block 65: calculated checksum 89D8 but expected 0 pg_verify_checksums: checksum verification failed in file "data/base/16384/28648", block 65: calculated checksum 9636 but expected 0 Checksum scan completed Data checksum version: 1 Files scanned: 2493 Blocks scanned: 13172 Bad checksums: 3 The files in question correspond to hash_i4_index hash_name_index hash_txt_index Discuss. ;-) -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
