Description

Adds the missing postgres introspection coverage and aligns the CLI surface with what the backend can actually deliver.

• schema-object introspection families: partitions, routines, types, operators, operator classes, operator families
• identity sequences and identity/auto-increment column facts
• DDL CLI type removed because supports_ddl_extraction() is now honestly False

The ddl introspection type is no longer advertised for this backend because
supports_ddl_extraction() is permanently False. introspect ddl is now an
argparse usage error (exit 2); the backend DDL expression/formatter remains for
a future implementation.

Adds # (no linked issue; operator-directed introspection coverage work)

Type of change

• feat: A new feature
• docs: Documentation only changes
• test: Adding missing tests or correcting existing tests
• ci: Changes to CI configuration files and scripts
• perf
• chore
• build
• revert

Breaking Change

• Yes
• No

The removed ddl CLI type never produced an answer for an ordinary table, so
its removal changes the help/type surface rather than a working capability.

Applicable rhosocial-activerecord Version Range:

>=1.0.0.dev30,<2.0.0

Related Repositories/Packages

• rhosocial-activerecord core: release/v1.0.0.dev30
• rhosocial-activerecord-testsuite: release/v1.0.0.dev17
• This backend's own release branch: release/v1.0.0.dev17

Testing

• CI run 42592033149: success (all jobs)
• Local offline tests: 227 offline introspection tests; 792 conformance/DDL expression tests
• introspect --help no longer lists ddl
• introspect ddl exits 2 with invalid choice

Test Plan:

The CI run above is the full matrix. Targeted offline suites cover the new
formatters, parsers, sync/async dispatch, capability gates and CLI vocabulary.

Checklist

• My code follows the project's code style guidelines.
• I have performed a self-review of my own code.
• I have commented my code, particularly in hard-to-understand areas.
• I have made corresponding changes to the documentation.
• My changes generate no new warnings.
• I have added a Changelog fragment (changelog.d/<pr_number>.<type>.md).
  Not added: the operator explicitly requested no changelog fragments.
• I have verified that my changes do not introduce SQL injection vulnerabilities.
• I have checked for potential performance regressions.

Additional Notes

The backend capability/formatter for DDL extraction is intentionally left in
place; only the CLI type was removed until a real implementation exists.
