Consumers writing a SQL binding need a running database to test
against. Extend the services block with two new keys:
services:
postgres: true
mysql: true
Unlike redis/nats (binaries installed on PATH; tests spawn them),
postgres and mysql are heavier: the action installs the server AND
starts it AND creates a test user + database, then exports the
connection URL as a well-known env var.
service_postgres=true → POSTGRES_TEST_URL=postgres://mcpg:mcpg@localhost/mcpg_test
service_mysql=true → MYSQL_TEST_URL=mysql://mcpg:mcpg@127.0.0.1/mcpg_test
Tests read the env var directly; no in-test server spawning
needed. Credentials are standardized so integration tests across
consumers don't have to negotiate.
Linux-only (same as redis/nats). Warning on non-Linux runners.
Self-test gets two new asserts on the skip path.
