Breaking Changes

●Issue #1

The default behavior for caching in `Pg` has changed. Caching is now only applied when explicitly configured, whereas previous beta versions applied caching even without explicit configuration.

Migration Steps

  1. 1
    Review `Pg` configurations to explicitly enable caching if it was previously relied upon implicitly.
  2. 2
    If using introspection on MySQL, verify generated schemas where relation names previously collided with column names, as they have been renamed to append `Relation`.

Release Summary

This release standardizes timezone handling for PostgreSQL timestamps and significantly improves the stability and correctness of `drizzle-kit` introspection and schema generation, especially for MySQL and complex indexing scenarios. Caching behavior in Pg has also been made explicit.
