When converting a database to PostgreSQL via `occ db:convert-type`,
the sequence resynchronization crashes on orphaned sequences that
no longer have an associated column (e.g. after autoincrement was
removed via dropAutoincrementColumn in a migration).
The query against information_schema.columns returns no row for
these sequences, and the code tried to access fields on a `false`
result, producing malformed SQL like:
SELECT setval('...', (SELECT MAX() FROM ))
Skip sequences with no matching column. Also handle empty tables
where MAX returns NULL, and use schema-qualified table names.
