* feat: create `sqlx.toml` format
* feat: add support for ignored_chars config to sqlx_core::migrate
* chore: test ignored_chars with `U+FEFF` (ZWNBSP/BOM)
https://en.wikipedia.org/wiki/Byte_order_mark
* refactor: make `Config` always compiled
simplifies usage while still making parsing optional for less generated code
* refactor: add origin information to `Column`
* feat(macros): implement `type_override` and `column_override` from `sqlx.toml`
* refactor(sqlx.toml): make all keys kebab-case, create `macros.preferred-crates`
* feat: make macros aware of `macros.preferred-crates`
* feat: make `sqlx-cli` aware of `database-url-var`
* feat: teach macros about `migrate.table-name`, `migrations-dir`
* feat: teach macros about `migrate.ignored-chars`
* chore: delete unused source file `sqlx-cli/src/migration.rs`

* WIP feat: create multi-tenant database example
* fix(postgres): don't fetch `ColumnOrigin` for transparently-prepared statements
* feat: progress on axum-multi-tenant example
* feat(config): better errors for mislabeled fields
* WIP feat: filling out axum-multi-tenant example
* feat: multi-tenant example
No longer Axum-based because filling out the request routes would have distracted from the purpose of the example.
* chore(ci): test multi-tenant example
* fixup after merge
* fix(ci): enable `sqlx-toml` in CLI build for examples
* fix: CI, README for `multi-tenant`

* fix: remove unused imports
* fix: doctest
* fix: `sqlx mig add` behavior and tests
* fix: restore original type-checking order
* fix: deprecation warning in `tests/postgres/macros.rs`
* feat: create postgres/multi-database example
* fix: examples/postgres/multi-database
* fix: cargo fmt
* chore: add tests for config `migrate.defaults`
* fix: sqlx-cli/tests/add.rs
* feat(cli): add `--config` override to all relevant commands
* chore: run `sqlx mig add` test with `RUST_BACKTRACE=1`
* fix: properly canonicalize config path for `sqlx mig add` test
* fix: get `sqlx mig add` test passing
* fix(cli): test `migrate.ignored-chars`, fix bugs
* feat: create `macros.preferred-crates` example
* fix(examples): use workspace `sqlx`
* fix: examples
* fix(sqlite): unexpected feature flags in `type_checking.rs`
* fix: run `cargo fmt`
* fix: more example fixes
* fix(ci): preferred-crates setup
* fix(examples): enable default-features for workspace `sqlx`
* fix(examples): issues in `preferred-crates`
* chore: adjust error message for missing param type in `query!()`
* doc: mention new `sqlx.toml` configuration
* chore: add `CHANGELOG` entry
Normally I generate these when cutting the release, but I wanted to take time to editorialize this one.
* doc: fix new example titles
* refactor: make `sqlx-toml` feature non-default, improve errors
* refactor: eliminate panics in `Config` read path
* chore: remove unused `axum` dependency from new examples
* fix(config): restore fallback to default config for macros
* chore(config): remove use of `once_cell` (to match `main`)
Inlined format args make code more readable, and code more compact.
I ran this clippy command to fix most cases, and then cleaned up a few trailing commas and uncaught edge cases.
```
cargo clippy --bins --examples --benches --tests --lib --workspace --fix -- -A clippy::all -W clippy::uninlined_format_args
```
**General**
* Moves `examples/postgres/realworld` to `examples/realworld`
* The app is now architected to support multiple DBs
* Adds feature flags for `sqlite` and `postgres` to allow user to choose
which backend to use
*NOTE* Currently it is not possible to compile with `postgres` and `sqlite`
enabled as we are using the `query!` and `query_as!` macros and they
seem to get unhappy.
* Adds CLI flags for picking the DB backend to use at runtime
* Adds schema file and implementation for SQLite for `/api/user` routes
* Adds stub routes and trait for articles and Articles entity
**Changes**
* We now use i32 instead of i64 as the user_id to get around some quirks
w/ the SQLite driver.
* Reimplements existing route handlers w/ an error handling shim so we can use
Try inside the biz logic
* *FIX* Adds a `user` key to the register user body to conform w/ realworld's
API specs
APIs were functionally tested using realworld's API test script
