Add pglite support

[ai]

PostgreSQL now have the similar file-based approach without server—pglite.

Maybe we can consider adding pglite support to the app?

Nice. Yes, this would be useful to add at some point. Are there Rust bindings for it?

I found https://github.com/kshcherban/pglite-rust-bindings in related issue electric-sql/pglite#470

Looks like it is in very young state, but people are playing with some solutions.
