Add SQLx operation tracing (#5223)

* wip: vendor sqlx-tracing

* (compiles) standardize pg types used

* more standardization

* general log message improvements

* wip: improve sqlx-tracing architecture

* unify sqlx::Executor type

* wip: try fix sqlx tracing

* wip: sqlx-tracing compiles

* so close

* it compiles

* fix ci
