It probablly comes from 'var-varlena' feature in 8.3. Now we store
text fields in a compact format on disks and extract them on access.
It consumes some CPU cycles. If all of data are in buffer cache
and the encoding of database is single-byte encodings, the performance
of LIKE in 8.3 was 10-20% slower than 8.2 on my tests.
