* [PATCH v2] Avoid orphaned objects dependencies
@ 2024-03-29 15:43 Bertrand Drouvot <[email protected]>
  0 siblings, 0 replies; 2179+ messages in thread

From: Bertrand Drouvot @ 2024-03-29 15:43 UTC (permalink / raw)

It's currently possible to create orphaned objects dependencies, for example:

Scenario 1:

session 1: begin; drop schema schem;
session 2: create a function in the schema schem
session 1: commit;

With the above, the function created in session 2 would be linked to a non
existing schema.

Scenario 2:

session 1: begin; create a function in the schema schem
session 2: drop schema schem;
session 1: commit;

With the above, the function created in session 1 would be linked to a non
existing schema.

To avoid those scenarios, a new lock (that conflicts with a lock taken by DROP)
has been put in place when the dependencies are being recorded. With this in
place, the drop schema in scenario 2 would be locked.

Also, after locking the object, the patch checks that the object still exists:
with this in place session 2 in scenario 1 would be locked and would report an
error once session 1 committs (that would not be the case should session 1 abort
the transaction).

The patch adds a few tests for some dependency cases (that would currently produce
orphaned objects):

- schema and function (as the above scenarios)
- function and type
- table and type

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use CREATE OR REPLACE FUNCTION to handle the
optional pretty argument.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 2179+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

set the pretty parameter.

* [PATCH v5 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 2179+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v4 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>
  0 siblings, 0 replies; 2179+ messages in thread

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v5 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v7 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8.1 5/6] Handle pg_get_expr default args in system_functions.sql
@ 2025-12-09 19:17 Mark Wong <[email protected]>

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.

* [PATCH v8 5/6] Handle pg_get_expr default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:17 UTC (permalink / raw)

Modernize pg_get_expr to use proargdefaults to handle the optional
pretty argument.  That also means any direct function calls now needs to
set the pretty parameter.
