Comment (by neteler):

 Here some code which could probably support the implementation:

 * https://github.com/OSGeo/grass-
 addons/blob/master/grass7/general/g.compare.md5/g.compare.md5.py

 For SQLite table sizes (apparently not easy to obtain):

 * https://stackoverflow.com/questions/27572387/query-that-returns-the-
 size-of-a-table-in-a-sqlite-database#36627097

 Hence (https://www.sqlite.org/dbstat.html):
 {{{
 sqlite3 nc_spm_08_grass7/PERMANENT/sqlite/sqlite.db

 # page size
 sqlite> SELECT SUM("pgsize") FROM "dbstat" WHERE name='zipcodes_wake';
 5120
 sqlite> SELECT SUM("pgsize") FROM "dbstat" WHERE name='roadsmajor';
 12288
 }}}
