Three consecutive waves (#1972 → #2015 → #2084) fixed pooler-teardown bugs
verified only against one production deployment — CI had no transaction-mode
pooler and could never see the class. Now it can:
- docker-compose.ci.yml: `pgbouncer` service (transaction pooling) fronting
postgres-1, mirroring the production split-pool topology (direct :5432 +
pooled :6543). AUTH_TYPE=plain (pg16 SCRAM verifiers need the plaintext
password in the userlist) + IGNORE_STARTUP_PARAMETERS for the
statement_timeout/idle_in_transaction_session_timeout startup params
gbrain's client sets (the Supabase pooler whitelists the same).
- test/e2e/pgbouncer-teardown.test.ts: schema + fixture via the DIRECT url
into a dedicated `gbrain_pgbouncer` database (never races shard TRUNCATEs),
then spawns the real CLI against the POOLED url and asserts: exit 0,
stdout intact (the #1959 truncation class), and NO
"did not return within 10000ms — force-exiting" banner (pre-#2084 it
printed on 100% of query-shaped ops on this topology). Class bound, not
exact timing. Skips gracefully without GBRAIN_PGBOUNCER_URL.
- scripts/ci-local.sh: threads GBRAIN_PGBOUNCER_URL +
GBRAIN_PGBOUNCER_DIRECT_URL into all three e2e phases.
Verified live: both tests green against pgbouncer 1.25.2 in transaction mode.
