-- PostgreSQL schema for Biz Connect — the target of the SQLite→Postgres migration.
--
-- Every column is defined up front here (unlike the SQLite db.js, which layers columns via ALTER TABLE
-- and hit a real ordering bug). Type mapping from the SQLite schema:
--   SQLite INTEGER epoch-ms timestamp  -> BIGINT     (ms since epoch; JS Number-safe)
--   SQLite INTEGER 0/1 boolean flag    -> SMALLINT   (kept numeric so app code still reads 0/1)
--   SQLite INTEGER byte size / duration-> BIGINT     (files can exceed INT range)
--   SQLite INTEGER small count (peak)  -> INTEGER
--   SQLite AUTOINCREMENT rowid         -> BIGINT GENERATED ALWAYS AS IDENTITY
--   TEXT                               -> TEXT
-- Foreign keys mirror the three the SQLite schema enforced (users→teams, sessions_auth→users,
-- machines→teams). The data-migration script inserts in dependency order so these hold.
