Two Postgres-only bugs found by a live docker-pg roundtrip (SQLite tests
passed because neither reproduces on SQLite):
- Export: knex `.stream()` pulls in the optional `pg-query-stream` module
(not bundled) and throws on pg. Switched to a plain per-table `select`
— works on both engines, no new dependency. Rows are DB metadata
(blobs live under files/), so holding a table in memory is fine.
- Import: the pg driver returns json/jsonb columns as parsed JS values,
so re-inserting a scalar like the string "PicPeak" sent it unquoted and
pg rejected it ("invalid input syntax for type json"). Now introspects
each table's json/jsonb columns and re-serialises those values before
insert (pg only; SQLite stores json as TEXT and round-trips as-is).
Verified end-to-end on docker Postgres: export 85 tables, full-override
import, current account preserved, post-backup data removed.
