Version 1.4.1, released 2026-06-29

Enhancements:
- test/: a Dockerfile parameterised by PG_MAJOR plus run-tests.sh and
  run-installcheck.sh to build and run "make installcheck" against every
  supported major version in throwaway containers.  Not-yet-released
  versions (currently 19) are pulled from the pgdg-snapshot repository.
- CI: add PostgreSQL 19 to the regression matrix.
- README: document all of the *_permissions views with worked examples,
  add a desired-vs-actual walkthrough built around permission_diffs() and
  the updatable views, and add a Compliance section relating the extension
  to common regulatory frameworks.

Version 1.4, released 2025-08-04

Bugfixes:
- Match a literal underscore in the "pg\_%" LIKE pattern so that schemas
  whose names merely start with "pg" (such as "pgabc123") are no longer
  mistaken for system schemas and excluded from the views.

Enhancements:
- Add a containerised regression test harness (in "test/") that builds the
  extension and runs "make installcheck" against PostgreSQL 12 through 19,
  pulling not-yet-released versions from the pgdg-snapshot repository.
- Add PostgreSQL 19 to the continuous integration matrix.
- Expand the documentation with worked examples for every "*_permissions"
  view, a walkthrough comparing the desired and actual state with
  "permission_diffs()" and the updatable views, and a section relating the
  extension to common compliance frameworks.

Version 1.3, released 2024-06-12

Enhancements:
- Support the MAINTAINprivilege new in PostgreSQL v17.

Version 1.2, released 2024-02-16

Enhancements:
- Add sequence to "permission_target" for ease of use.

  Idea by Srikanth Medikonda.

Version 1.1, released 2018-12-19

Enhancements:
- Add triggers to the permission views to make them updatable.
  Updating will issue GRANT or REVOKE statements.

  Patch by Antonin Houska.

Bugfixes:
- Rename the "permissions" column of "schema_permissions" and
  "database_permissions" to "permission" to match the other views.
