From e117e607f48d1704b046061acad0f5455457c569 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 19 Feb 2026 20:15:56 +0000 Subject: [PATCH 1/4] Add sqlc-test-setup command for database test environment setup New cmd/sqlc-test-setup package with two subcommands: - `install`: Installs PostgreSQL and MySQL 9 via apt, including apt proxy configuration for Claude Code remote environments. - `start`: Starts both database services, configures authentication (passwords, pg_hba.conf), and verifies connectivity.
