In PostgreSQL, Liquibase maps the `blob` type to an `oid` column by
default[1]. That column type is not supported[2] very well when using
the `valueBlobFile` attribute, which expects a `bytea` column instead.
This was confirmed on all PostgreSQL versions starting from 9.6.
The `validCheckSum` attribute does not need to be updated since it was
already for the previous (binary_type, varchar_type) combination in
an unrelated commit (78a99d5860).
Fixes #1213.
