What this is

If a Query Tool result set includes a calculated or aliased column (e.g. first_name || ' ' || last_name AS the_name), editing any cell on an existing row and saving throws column "the_name" does not exist. The frontend already marks such columns non-editable (shown with a lock icon), but save_changed_data()'s update path still passed them through when rendering the UPDATE statement.

The insert path already had this guard, added for #9939; the update path just never got the equivalent filter.

Fix

save_changed_data() now drops any key not present in columns_info, or explicitly marked is_editable: False, before rendering the UPDATE, in both the insert and update code paths.

Fixes #10103.

Test plan

  • Added TestSaveUpdatedRowSkipsNonEditableColumn, mirroring the existing insert-path test for Query Editor Cannot Recognize Non-Updatable Fields #9939.
  • regression/runtests.py --pkg tools.sqleditor.utils.tests.test_save_changed_data — 14/14 passed.
  • regression/runtests.py --pkg tools.sqleditor — 158 passed, 3 pre-existing/unrelated skips.
  • pycodestyle clean.

Review Change Stack

Walkthrough

Changes

Role membership permissions

Layer / File(s) Summary
ADMIN OPTION permission contract
web/pgadmin/browser/server_groups/servers/roles/__init__.py, web/pgadmin/browser/server_groups/servers/roles/templates/roles/sql/default/permission.sql
Role permission queries return has_admin_option, and authorization loads this value before checking permissions.
Membership-only update enforcement
web/pgadmin/browser/server_groups/servers/roles/__init__.py, web/pgadmin/browser/server_groups/servers/roles/tests/test_role_check_permission_unit_test.py
Users with ADMIN OPTION can update rolmembers; other updates remain forbidden. Tests cover ordinary users, ADMIN OPTION users, role drops, and superusers.
Membership editing controls
web/pgadmin/browser/server_groups/servers/roles/static/js/role.ui.js, web/regression/javascript/schema_ui_files/role.ui.spec.js
The role UI allows membership changes for ADMIN OPTION users and retains read-only behavior for other users.

Concurrent REINDEX SQL

Layer / File(s) Summary
REINDEX command generation and expectations
web/pgadmin/tools/maintenance/templates/maintenance/sql/command.sql, web/pgadmin/tools/maintenance/tests/test_maintenance_create_job_unit_test.py
REINDEX statements now place CONCURRENTLY after the target object type. Tests update database, table, and index expectations.

Query result update filtering

Layer / File(s) Summary
Editable column filtering
web/pgadmin/tools/sqleditor/utils/save_changed_data.py, web/pgadmin/tools/sqleditor/utils/tests/test_save_changed_data.py
Update SQL excludes unknown and non-editable columns. Regression coverage verifies that aliased expression columns are not updated.

Server validation and cursor execution

Layer / File(s) Summary
Non-shared username validation
web/pgadmin/utils/__init__.py, web/pgadmin/utils/tests/test_validate_json_data.py
Non-shared servers reject empty or null Username values.
Transaction control with server cursors
web/pgadmin/utils/driver/psycopg3/connection.py, web/pgadmin/utils/driver/psycopg3/tests/test_execute_void_server_cursor.py
execute_void uses a temporary plain cursor for COMMIT and ROLLBACK when a server cursor is cached, then clears stale result state.

Helm authentication secret references

Layer / File(s) Summary
Authentication secret conditions
pkg/helm/templates/deployment.yaml
Deployment annotations and secret checksum conditions now use .Values.auth.existingSecret.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 767c8

This change set currently includes unresolved failures that can reject valid role updates, return stale query results after void operations, and allow invalid server-import data to persist; it also permits unsupported reindex flag combinations to silently change behavior, so it is not merge-ready until these issues are fixed or explicitly accepted.

Add coverage for concurrent SCHEMA reindexing.

The updated cases cover DATABASE, TABLE, and INDEX. The template also changes the SCHEMA branch at command.sql Line 27, but this test file has only a non-concurrent SCHEMA case. Add a concurrent SCHEMA scenario.

Rebased this branch onto current upstream/master and dropped 5 commits that had ridden along from an unrelated local development stack: #10214 (Helm existingSecret fix), #10251 (REINDEX CONCURRENTLY fix), #9450 (role admin-option membership feature), #10309 (username-import fix, already merged as part of #10320), and #8991 (server-cursor fix). None of those were part of this PR's actual change; the branch now carries only the one commit for the alias/expression column exclusion.

As a result, the diff no longer touches roles/__init__.py, web/pgadmin/tools/maintenance/, utils/__init__.py, or psycopg3/connection.py - all four of CodeRabbit's outstanding review threads were on code from those dropped commits, not on this PR's own change, so I've resolved them as moot. Force-pushed the cleaned-up branch.
