- I-1: QuestDbConnection caps Npgsql Maximum Pool Size at 24 (DefaultMaxPoolSize)
when the connection string does not set it; an explicit value is kept. The
effective value is logged once at Information.
- M-1: QuestDbTagCatalog.EnsureAsync waits for the tag table's sequenced commits
and re-checks before inserting, so it no longer overwrites a provisioner row
(unit/description) that is committed but not yet applied. Integration test
reproduces the clobber against real QuestDB (falsified).
- M-3: the pre-1970 drop Warning is rate-limited per tag (once per 10 min);
DroppedPre1970 still counts every sample.
- M-5: QuestDbHistorianProvider is IAsyncDisposable/IDisposable and disposes the
shared Npgsql pool; Program.cs registers the provider through a factory and
every seam resolves it from the container, so DI disposes it at shutdown.
- M-8, M-9: docs fixes (HistoryUpdate transaction wording; folded duplicate
HistoryUpdate paragraph). Pool-size docs updated for the new default cap.
