Subject: [PATCH 18/46] feat(extensions): add Protocol and Mixin for 17 new PostgreSQL extensions Implemented support for the following extensions: - pg_cron: job scheduling - citext: case-insensitive text - bloom: bloom filter index - pg_partman: partition management - orafce: Oracle compatibility - pglogical: logical replication - pgaudit: audit logging - pg_repack: online rebuild - hypopg: hypothetical indexes - address_standardizer: address parsing - pg_surgery: data repair - pg_walinspect: WAL inspection - fuzzystrmatch: fuzzy string matching - cube: multidimensional cube - pgcrypto: cryptographic functions - btree_gin: GIN index for btree types - btree_gist: GiST index for btree types - uuid-ossp: UUID generation --- .../postgres/mixins/extensions/__init__.py | 36 +++++

Override PostgresDialect.format_binary_operator to escape % as %% for psycopg compatibility (pg_trgm similarity operator) - Add PostgresIndexMixin.format_create_index_statement for CREATE INDEX with operator classes via dialect_options["opclasses"] - Move PostgresIndexMixin before IndexMixin in PostgresDialect MRO to ensure override takes effect - Remove blind sql.replace("?", "%s") in PostgresBackendMixin that broke hstore/jsonb ? operators - Add uuid_ns_dns/url/oid/x500 helper functions returning FunctionCall - Replace all RawSQLExpression usage in 12 extension examples with proper expression API (Literal.cast(), FunctionCall, Subquery, etc.) - Fix cube range data format from invalid (a,b),(c,d),(e,f) to correct (min_point),(max_point) - Fix result data access from integer index to dict key access - Fix uuid_generate_v5 namespace parameter to use uuid_ns_dns() instead of string literal - Remove uuid_max() call (not available in current PG versions) Co-Authored-By: Claude Opus 4.6 --- .../backend/impl/postgres/backend/base.py | 13 +- .../backend/impl/postgres/dialect.py | 20 +- .../impl/postgres/examples/extensions/cube.py | 47 +++-- .../examples/extensions/earthdistance.py | 2 +- .../examples/extensions/fuzzystrmatch.py | 36 ++-- .../postgres/examples/extensions/hstore.py | 15 +- .../postgres/examples/extensions/intarray.py | 5 +- .../postgres/examples/extensions/pg_trgm.py | 1 + .../postgres/examples/extensions/pgcrypto.py | 6 +- .../postgres/examples/extensions/pgvector.py | 31 +-- .../postgres/examples/extensions/postgis.py | 15 +- .../postgres/examples/extensions/uuid_ossp.py | 36 ++-- .../impl/postgres/functions/__init__.py | 8 + .../backend/impl/postgres/functions/uuid.py | 177 +++++++++++++----- .../backend/impl/postgres/mixins/ddl/index.py | 79 ++++++++ 15 files changed, 342 insertions(+), 149 deletions(-) diff --git a/src/rhosocial/activerecord/backend/impl/postgres/backend/base.py b/src/rhosocial/activerecord/backend/impl/postgres/backend/base.py index 4a4b45ac..6e7b6f33 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/backend/base.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/backend/base.py @@ -31,14 +31,13 @@ def _prepare_sql_and_params(self, sql: str, params: Optional[Tuple]) -> Tuple[st """ Prepare SQL and parameters for PostgreSQL execution. -

__init__.py: subcommand registration and dynamic dispatch - output.py: provider factory and RICH_AVAILABLE - connection.py: connection args, config resolution, backend creation - info.py: info subcommand with protocol display (26 Postgres Protocols) - query.py: query subcommand (sync + async) - introspect.py: introspect subcommand with 'extensions' type - status.py: status subcommand with WAL/Replication/Archive/Security sections - named_query.py: named-query adapter using closures - named_procedure.py: named-procedure adapter using closures - named_connection.py: named-connection adapter with empty parent parser Key changes: - Remove global _default_backend variable, use closure-based approach - Move -v/--verbose from main parser to info/status subcommands only - Each subcommand independently decides its own arguments - Rename test_cli.py to test_named_connection_cli.py for clarity - Update mock paths from __main__ to cli.connection module --- .../backend/impl/postgres/__main__.py | 1767 +---------------- .../backend/impl/postgres/cli/__init__.py | 34 + .../backend/impl/postgres/cli/connection.py | 138 ++ .../backend/impl/postgres/cli/info.py | 501 +++++ .../backend/impl/postgres/cli/introspect.py | 374 ++++ .../impl/postgres/cli/named_connection.py | 32 + .../impl/postgres/cli/named_procedure.py | 112 ++ .../backend/impl/postgres/cli/named_query.py | 115 ++ .../backend/impl/postgres/cli/output.py | 50 + .../backend/impl/postgres/cli/query.py | 205 ++ .../backend/impl/postgres/cli/status.py | 553 ++++++ ...st_cli.py => test_named_connection_cli.py} | 30 +- .../feature/backend/test_cli.py | 2 +- 13 files changed, 2150 insertions(+), 1763 deletions(-) create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/__init__.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/connection.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/info.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/introspect.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/named_connection.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/named_procedure.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/named_query.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/output.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/query.py create mode 100644 src/rhosocial/activerecord/backend/impl/postgres/cli/status.py rename tests/rhosocial/activerecord_postgres_test/feature/backend/named_connection/{test_cli.py => test_named_connection_cli.py} (74%) diff --git a/src/rhosocial/activerecord/backend/impl/postgres/__main__.py b/src/rhosocial/activerecord/backend/impl/postgres/__main__.py index 9e8a0299..1c1761e1 100644 --- a/src/rhosocial/activerecord/backend/impl/postgres/__main__.py +++ b/src/rhosocial/activerecord/backend/impl/postgres/__main__.py @@ -1,1778 +1,51 @@ # src/rhosocial/activerecord/backend/impl/postgres/__main__.py -""" -PostgreSQL backend command-line interface. +"""PostgreSQL backend command-line interface. -Provides SQL execution and database information display capabilities. +Provides SQL execution and database introspection capabilities.

Remove `tests.` prefix from module paths in integration tests. The `tests.rhosocial...` import paths only worked with `python -m pytest` (CWD in sys.path makes `tests` an implicit namespace package). Direct `pytest` does not add CWD to sys.path, causing ModuleNotFoundError. Fix by using `rhosocial.xxx` paths that work via PYTHONPATH entry. 2. Add `tests` to PYTHONPATH in CI to ensure `tests/rhosocial/` is searched as part of the namespace package path. 3. Enable autocommit on psycopg connections to prevent psycopg 3 from auto-managing transactions (which conflicts with manual BEGIN/COMMIT statements in the ActiveRecord layer). --- .github/workflows/test.yml | 4 ++-- .../backend/impl/postgres/backend/async_backend.py | 1 + .../backend/impl/postgres/backend/sync.py | 1 + .../backend/named_connection/test_resolver.py | 14 +++++++------- 4 files changed, 11 insertions(+), 9 deletions(-) diff --git a/.github/workflows/test.yml b/.github/workflows/test.yml index 46b3fb61..9b73e549 100644 --- a/.github/workflows/test.yml +++ b/.github/workflows/test.yml @@ -99,13 +99,13 @@ jobs: -
