Fix MAINTAIN privilege silently dropped for views/mviews on PG17+ by dpage · Pull Request #10354 · pgadmin-org/pgadmin4

dpage · 2026-08-26T14:12:51Z

Summary

_ALLOWED_PRIVS_JSON = 'sql/allowed_privs.json' in views/__init__.py expects the allowed-privileges list under a sql/ subdirectory of each version bucket, matching the default bucket's layout. The PG17+ allowed_privs.json files for views and materialized views (both pg and ppas) were added directly under the 17_plus bucket directory instead, so render_template('views/pg/17_plus/sql/allowed_privs.json') never found them and silently fell through to the default bucket's list via the versioned template loader's fallback - which predates the MAINTAIN privilege and lacks 'm'.
Net effect: the MAINTAIN checkbox appears in the Grant Wizard for views/mviews on PG17+/EPAS17+, but ticking it and saving never actually grants MAINTAIN, because _parse_privileges drops any privilege not in allowed_acls.
Fix: moved the four affected allowed_privs.json files (views/mviews × pg/ppas) under sql/ to match the default bucket's layout, matching one of the two fixes the issue suggested and requiring no code changes.

Test plan

Added web/pgadmin/browser/server_groups/servers/databases/schemas/views/tests/test_allowed_privs_json_path.py, rendering the PG17 template path directly for all four combinations and asserting 'm' is present.
Confirmed all four scenarios fail against the pre-fix file layout (falling back to default, missing 'm') and pass with the fix.
Ran the full views.tests package - no regressions.
pycodestyle clean on the new test file.

Summary by CodeRabbit

New Features
- Added PostgreSQL 17+ support for managing privileges on views and materialized views.
- Added support for the MAINTAIN privilege across PostgreSQL and PPAS view objects.
- Added support for standard materialized-view privileges, including grants and revocations.
Bug Fixes
- Corrected privilege metadata loading for PostgreSQL 17+ view and materialized-view templates.
Tests
- Added regression coverage for PostgreSQL and PPAS privilege definitions, including quoted object names.

allowed_privs.json for the 17_plus bucket lived directly under the bucket directory instead of under a sql/ subdirectory like every other bucket (including default), so render_template() looked for views/pg/17_plus/sql/allowed_privs.json, didn't find it, and silently fell back to the default bucket's list - which predates MAINTAIN and lacks 'm'. Moved the four affected files (views/mviews x pg/ppas) to match the default bucket's layout. Closes pgadmin-org#10350

Walkthrough

Added PostgreSQL and PPAS 17+ ACL definitions for views and materialized views. Added regression and SQL coverage for template loading, MAINTAIN, and materialized-view privilege grants.

Changes

View privilege metadata

Layer / File(s)	Summary
PG17 privilege templates `web/pgadmin/browser/server_groups/servers/databases/schemas/views/templates/.../17_plus/sql/allowed_privs.json`	Added `VIEW` and `MVIEW` `datacl` definitions for PostgreSQL and PPAS with supported ACL privileges.
Privilege handling validation `web/pgadmin/browser/server_groups/servers/databases/schemas/views/tests/test_allowed_privs_json_path.py`, `web/pgadmin/browser/server_groups/servers/databases/schemas/views/tests/{pg,ppas}/17_plus/*`	Added coverage for all four PG17+ templates, verified the `MAINTAIN` privilege, and added materialized-view privilege grant statements.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to ab01c

The change restores MAINTAIN privilege handling for PostgreSQL and EPAS 17+ views and materialized views by placing the privilege definitions where they are loaded, with targeted and package-level tests passing. No actionable merge-blocking risk remains.

Now that allowed_acls for views/mviews correctly includes MAINTAIN on PG17+, granting the same non-MAINTAIN privilege set as before no longer equals the full allowed set, so the generated SQL expands to the explicit privilege list instead of collapsing to "GRANT ALL" - this is the correct new behaviour, but it left the two mview msql fixtures (which fell back to the default bucket, written before MAINTAIN existed) stale. Added 17_plus overrides with the corrected expected output, alongside the existing 15_plus/16_plus buckets for these fixtures.

Review

The core fix is correct and working as expected. ViewNode.BASE_TEMPLATE_PATH = 'views/{0}/#{1}#' plus _ALLOWED_PRIVS_JSON = 'sql/allowed_privs.json' resolves views/pg/#170000#/sql/allowed_privs.json, and VersionedTemplateLoader falls back per-file, so a 17_plus/allowed_privs.json without the sql/ level was genuinely unreachable. Moving the four files is the right minimal fix, nothing references the old paths, and the schemas/catalog templates that also keep allowed_privs.json at the bucket root are consistent with their own _ALLOWED_PRIVS_JSON value, so no wider cleanup is needed.

Two problems with the test-fixture half, though.

1. The new `17_plus` test folders will silently disable the entire views/mviews RE-SQL suite on PG17+

get_test_folder() (web/regression/re_sql/tests/test_resql.py:380-410) picks the first existing version directory and then os.listdirs it for .json scenario files — folder-level resolution, unlike get_test_file(), which falls back per file. That is why every other bucket (pg/15_plus, pg/16_plus, …) duplicates tests.json and test_mview.json.

The new views/tests/pg/17_plus and views/tests/ppas/17_plus contain only the two .sql files, so on a PG17+ server the runner resolves to those directories, finds zero JSON files, and runs no view/mview RE-SQL scenarios at all — including the ones this PR is trying to pin down. Both new directories need copies of tests.json and test_mview.json.

2. The RE-SQL (non-msql) fixtures for the same two scenarios are now stale as well

The sql() path re-filters through parse_priv_to_db(..., allowed_acls) (views/__init__.py:1487-1492), so the same ALL-collapse rule in parse_priv_to_db applies to reverse-engineered SQL too. Both affected scenarios grant the 7-privilege set to PUBLIC, and their expected RE-SQL still reads GRANT ALL ... TO PUBLIC:

views/tests/pg/default/alter_mview.sql:17 and views/tests/ppas/default/alter_mview.sql:17
views/tests/pg/default/alter_mview_change_grantee_priv.sql:17 and views/tests/ppas/default/alter_mview_change_grantee_priv.sql:17

These need 17_plus overrides with the explicit privilege list, exactly like the msql fixtures added here.

The TO <OWNER> lines and the alter_mview_drop_all_priv* fixtures are fine — the owner's PG17 ACL includes m, so 8-of-8 still collapses to ALL.

Minor

test_allowed_privs_json_path.py overrides setUp to pass, which skips the server connection but still relies on the regression harness for self.app. That works given how BaseTestGenerator is wired, it is just unusual for this directory.
