Suspiciously fast auto-increment speed in the table

Hi there!

I noticed that after restarting an node.js application that uses pglite and auto-increment, the auto-increment value increases by more than one—sometimes by ten, for example. I'm not sure if this is a bug or a feature, so I decided to create a sandbox and explain how to reproduce it.

Also the same case reproducible in browser with usage of IndexedDB for persistence.

Here sandbox https://codesandbox.io/p/devbox/pglite-test-case-tyzvn7 in which you can reproduce the case.

Just go to terminal and restart application with `ctrl + c` and that by re-run app by command `npm install && npm start`. You will see that the auto-increment for new rows increases by more than one.
