* [PATCH v3 7/7] Handle pg_get_triggerdef default args in system_functions.sql

From: Mark Wong @ 2025-12-09 19:51 UTC (permalink / raw)
Modernize pg_get_triggerdef to use CREATE OR REPLACE FUNCTION to handle
the optional pretty argument.

* [PATCH v6] contrib/sslinfo: Add ssl_group_info
@ 2026-05-13 17:51 Dmitrii Dolgov <[email protected]>
0 siblings, 0 replies; 190+ messages in thread
From: Dmitrii Dolgov @ 2026-05-13 17:51 UTC (permalink / raw)
Add a new function to sslinfo ssl_group_info to show SSL groups,
including negotiated, supported and shared. It's useful for diagnostic
purposes, to identify what's being used and supported, e.g. which key
share is being negotiated. Few examples, for openssl 3.2.4:
select * from ssl_group_info();
type | name
------------+--------------------
negotiated | X25519MLKEM768
shared | X25519MLKEM768
shared | x25519
supported | X25519MLKEM768
supported | x25519
[...]
The implementation is inspired by ssl_print_groups from openssl.
