Consistently truncate non-key suffix columns. INCLUDE indexes failed to have their non-key attributes physically truncated away in certain rare cases. This led to physically larger pivot tuples that contained useless non-key attribute values. The impact on users should be negligible, but this is still clearly a regression (Postgres 11 supports INCLUDE indexes, and yet was not affected).
The bug appeared in commit dd299df8, which introduced "true" suffix truncation of key attributes.
