Registers the 'named-migration' CLI subcommand for the PostgreSQL backend. Delegates to the shared implementation in rhosocial.activerecord.backend.migration.cli. - cli/named_migration.py: parser + handler adapter - cli/__init__.py: register in COMMAND_NAMES and register_commands()
…ripts for PostgreSQL - Extend named_migration.py adapter with --async support (AsyncPostgresBackend) - Add extensive CLI epilog with 12 scenario examples and demo script references - Create examples/named_migrations/ with migrations.py, expressions.py, run_basic.py, run_chain.py - Add demo_basic.sh, demo_chain.sh, demo_all.sh end-to-end shell scripts - expressions.py uses PostgresSerialType and PostgresCharacterVaryingType

Description
This PR adds the
named-migrationCLI subcommand to the PostgreSQL backend adapter, enabling PostgreSQL users to leverage the named migration system introduced in corepython-activerecord(PR #109).Changes:
cli/named_migration.py): Registersnamed-migrationsubcommand with PostgreSQL-specific connection config and delegates torhosocial.activerecord.backend.migration.cli.handle_named_migration. Supports both sync (PostgreSQLBackend) and async (AsyncPostgreSQLBackend) execution.examples/named_migrations/): PostgreSQL-specific migration examples:migrations.py:V001CreateUsers,V002CreatePosts,V003CreateCustomTableexpressions.py: DDL expressions with PostgreSQL data typesrun_basic.py/run_chain.py: Programmatic API usagedemo_basic.sh/demo_chain.sh/demo_all.sh: Shell demo scriptsType of change

changelog.d/<pr_number>.added.mdAdditional Notes
This is the PostgreSQL plugin counterpart of the core migration feature (PR #109). The adapter is thin (~120 lines) — all core migration logic, dry-run validation, and record store management live in
rhosocial.activerecord.backend.migration.
