/**
 * Postgres migration set (D19). Numbered, applied in order by db-pg.ts's runner,
 * each inside its own transaction, recorded in schema_migrations. Inline strings
 * (not .sql files) so esbuild bundles them into dist/server.cjs with no file I/O.
 *
 * Translation choices vs the SQLite SCHEMA (deliberate, recorded in the D19 spec):
 * - every *_paise / money column is BIGINT (int4 overflows at ₹2.15 crore in paise);
 * - 0/1 flags stay INTEGER — repos say `active=1` and that SQL must be identical on
 *   both engines (boolean would break it);
 * - JSON payloads stay TEXT — node-pg auto-parses json/jsonb columns into objects,
 *   which would break the repos' JSON.parse at the edge. A jsonb ALTER is a later,
 *   pg-only optimisation if we ever index into payloads;
 * - dates stay TEXT ISO (house convention, index-friendly, no timezone surprises);
 * - the reminder.rule_kind CHECK is born in its final widened form (SQLite reaches
 *   it via the guarded table rebuild; Postgres starts correct).
