Invalidate cached INSERT metadata #295
Description
Something to be careful with this kind of caching is the user may make concurrent changes to the table which invalidates the cached metadata. This could easily happen if they run migrations during a rolling upgrade of an application.
We've had problems with this in SQLx WRT prepared statement caching.
This isn't necessarily a bad idea, but at the very least you should provide a method for the user to manually invalidate the cache.
