An instance of PostgreSQL crashing with a bad timing could leave behind temporary pg_internal.init files, potentially causing failures when verifying checksums. As the same exclusion lists are used between pg_rewind, pg_checksums and basebackup.c, all those tools are extended with prefix checks to keep everything in sync, with dedicated checks added for pg_internal.init. Backpatch down to 11, where pg_checksums (pg_verify_checksums in 11) and checksum verification for base backups have been introduced.
