Daan MeijerandClaude Opus 5.5 ef09c07d6e files.id migration in one transaction
Test and deploy / test (push) Successful in 1m51s
Test and deploy / deploy (push) Successful in 49s
A failure after the old parent is dropped would leave files half-converted;
in one transaction it rolls back completely. Tested on a fresh Postgres 17.

Daan MeijerandClaude Opus 5.5 9201e1200e files.id to 64 bits
Test and deploy / test (push) Successful in 1m52s
Test and deploy / deploy (push) Skipped
Seeding adds ~14M files a day; 32-bit ids run out at 2.1 billion in about
five months. Postgres can't change a partition key's type, so the
migration detaches the partitions, rewrites each as a plain table (a CHECK
added first spares the attach scan), and attaches them to a new 64-bit
parent with the same indexes, foreign keys and triggers. binaries.file_id
and the id sequence become 64-bit too. Meant to run with the writers
stopped and Postgres on wal_level=minimal (compose: PG_WAL_LEVEL,
PG_MAX_WAL_SENDERS).
