* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded

skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.

* [PATCH v3] Fix test_custom_stats modules to error out when not preloaded
@ 2026-07-02 04:34  Bertrand Drouvot <bertranddrouvot.pg@gmail.com>
  0 siblings, 0 replies; 323+ messages in thread

From: Bertrand Drouvot @ 2026-07-02 04:34 UTC (permalink / raw)

Previously, test_custom_var_stats and test_custom_fixed_stats silently
skipped pgstat_register_kind() when not loaded via shared_preload_libraries.
This left the SQL functions callable without the kind registered, leading to NULL
dereferences in core pgstat functions.

Remove the early return and let pgstat_register_kind() error out naturally,
matching the pattern used by test_custom_rmgrs with RegisterCustomRmgr(). Now
CREATE EXTENSION fails with a clear error if the module is not preloaded.
