We have run into queries that corrupted the database client-side, but fortunately that doesn't propagate into postgres itself. In that case we had to drop the client-side db and resync from a clean state.

The corruption was also caught by sqlite itself - it threw a "malformed disk image" error and stopped responding to any further queries.

Also bugs around syncing some kinds of data - one bug that's already been fixed was that floats without decimal points would not get synced. https://github.com/electric-sql/electric/issues/506

In general electric's team is very responsive and fixes bugs when we bring them up.

SQLite had 2 bugs[1] where batch atomic writes would corrupt your DB if you used IndexedDB to back your VFS. It has been patched in SQLite so rolling a new electric release that pulls in the latest SQLite build should fix that.

Any idea on what the root cause of the sqlite corruption was? There's some discussion on the SQLite forums about corruption with wasm (I've encountered it myself on a personal project), but from what I understand no one has identified a cause yet.
