minco-sqlx-postgres

Bounded SQLx PostgreSQL runtime support for Minco.

The serverless profile defaults to a small pool with zero minimum connections, a bounded acquisition timeout, and an idle timeout. Runtime and migration credentials should remain separate in deployed environments.

use minco_sqlx_postgres::{PostgresPoolConfig, connect};

# async fn open() -> Result<(), minco_sqlx_postgres::PostgresError> {
let config = PostgresPoolConfig::serverless("postgresql://localhost/app");
let pool = connect(&config).await?;
assert!(minco_sqlx_postgres::ready(&pool).await);
# Ok(()) }

Applications that compose independently versioned migration sets must give each set its own history table:

# use minco_sqlx_postgres::PgPool;
# async fn migrate(pool: &PgPool) -> Result<(), minco_sqlx_postgres::PostgresError> {
minco_sqlx_postgres::migrate_with_history_table(
    pool,
    "migrations/orders",
    "_minco_orders_migrations",
)
.await?;
# Ok(()) }

The history-table name is restricted to a plain PostgreSQL identifier. Reusing SQLx's default _sqlx_migrations table for unrelated migration directories causes version/checksum collisions.
