Message-ID: <E1ro9Y9-005Koh-Ot@gemulon.postgresql.org> (raw)
amcheck: Support for different header sizes of short varlena datum
In the heap, tuples may contain short varlena datum with both 1B header and 4B
headers. But the corresponding index tuple should always have such varlena's
with 1B headers. So, for fingerprinting, we need to convert.
Backpatch to all supported versions.
