⭐ StartPostgresql

StartPostgresql provisions PostgreSQL databases through the same 7-step pipeline every engine follows (see StartActions Overview). PostgreSQL's own specifics — SSL support, cert mount path, healthcheck probe — are covered in the database-provisioning-engines.html, alongside the other 7 engines, rather than repeated here.

Its healthcheck runs a real psql ... -c 'SELECT 1' query, not just a bare pg_isready connectivity check. Supports SSL/TLS through the shared SSL Subsystem.
