This is reproducible with PG11 and PG12:
initdb -k data
postgres -D data
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. ;-)
