@RuboGubo could you elaborate on what exactly you are thinking of? What kind of functionality, and for which of the formats? Thx!

Well, essentially the same as for the PostgreSQL implementation, Having the ability to encode and decode different geography into one column.

The GPKG driver does read from and write to SQLite using SQLx:

geozero/geozero/src/gpkg/mod.rs

Lines 11 to 25 in 9b3f6b4

//! use geozero::{wkb, ToWkt};
//! use sqlx::sqlite::SqlitePoolOptions;
//!
//! # async fn rust_geo_query() -> Result<(), sqlx::Error> {
//! let pool = SqlitePoolOptions::new()
//! .max_connections(5)
//! .connect("sqlite://points.gpkg")
//! .await?;
//!
//! let row: (wkb::Decode<geo_types::Geometry<f64>>,) = sqlx::query_as("SELECT geom FROM pt2d")
//! .fetch_one(&pool)
//! .await?;
//! if let Some(geom) = row.0.geometry {
//! println!("{}", geom.to_wkt().unwrap());
//! }

Writing is limited, since a spatial extension like SpatiaLite is required for most operations.

GDAL has two and a half SQLite drivers: https://gdal.org/drivers/vector/gpkg.html, https://gdal.org/drivers/vector/sqlite.html

Is your intention supporting non-GPKG SQLite?
