Hi,

I’ve hit the same issue as PGroonga GitHub Issue #233 [1]:
PGroonga-related files trigger pg_checksums verification
failures.

I’d like to propose a feature: Add support to pg_checksums for
excluding files matching custom patterns. This can handle
compatibility with extensions like PGroonga that generate files
within the PostgreSQL data directory.

Best regards,
XYenon
