[DATABASE][MariaDB] Always use LONGBLOB for "blob"

Browse Source 
"blob" is practically used with the expectation of unlimited length, which is
true with PostgreSQL's bytea, but not with MariaDB's BLOB, which is limited to
64KiB.
So instead use LONGBLOB, which has a maximum of 4GiB, effectively unlimited.
