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()'s update path now drops any key not present in columns_info, or explicitly marked is_editable: False, before rendering the UPDATE, matching the existing insert-path filter. A row left with nothing to write after filtering is skipped, rather than rendering an UPDATE with an empty SET clause.

Fixes #10103.

Test plan

  • Added TestSaveUpdatedRowSkipsNonEditableColumn, mirroring the existing insert-path test for Query Editor Cannot Recognize Non-Updatable Fields #9939, with scenarios for a real column updated alongside an alias and for an alias-only update.
  • regression/runtests.py --pkg tools.sqleditor.utils.tests.test_save_changed_data: 15/15 passed.
  • pycodestyle clean.

Summary by CodeRabbit

  • Bug Fixes
    • Updates to editable fields now succeed even when submitted data includes calculated or otherwise non-editable columns.
    • Submissions containing only non-editable fields no longer cause an update error or change the stored row.

Walkthrough

Updated-row data is filtered to include only known editable columns. Rows with no editable data are skipped. Tests cover updates that include a non-editable alias and updates containing only that alias.

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.

Filtering out non-editable columns can leave a row with nothing to write,
which would render an UPDATE with an empty SET clause and fail. Skip such
rows, and add a test scenario covering an alias-only update.
