server/db/schema.pg.sql — the full Postgres DDL, every column defined up front (no
ALTER-ordering fragility). SQLite→PG type mapping documented in-file (epoch-ms
INTEGER→BIGINT, 0/1 flags→SMALLINT kept numeric so app code is unchanged, sizes→
BIGINT, audit rowid→GENERATED IDENTITY). Mirrors the three existing FKs and adds a
new idx_messages_attachment (the /files auth scan we cached earlier becomes a keyed
lookup).
Validated against a throwaway Postgres 16: loads with no errors, 24 tables + 44
indexes created. Unwired — nothing uses it yet; the SQLite path is untouched.
