  1. ORCA: order-preserving LINT mapping for string statistics 

    Replace the hash-based LINT mapping used by ORCA's varchar/text/bpchar
statistics with an order-preserving 7-byte locale sort-key prefix, so
that single-column MCV and histogram estimates respect the column's
collation order instead of collapsing to hash values.

  1. PAX: fix pax_inject_fault flaky test 

    Move the failing INSERT inside -- start_ignore so non-deterministic
crash recovery messages (DETAIL/HINT/WARNING from postmaster killing
other backends after a PANIC) are prefixed with GP_IGNORE: by
atmsort.pm and ignored by the diff comparison.
