Hi Adrian, Thanks for the test, I installed also version 17.2 and test with a fresh newly created db. At the beginning I cannot reproduce the problem as well. Than I start adding the extension we use, one after one, and testing in between.
I found out that the problem appear immediately as soon as I add the extension pg_stat_statements: create extension pg_stat_statements WITH SCHEMA public; alter system set shared_preload_libraries = 'pg_stat_statements'; Can you maybe test as well with this extension? the other that I installed before that are: pgcrypto and pg_prewarm. here the current installed one: dbtest=# \dx List of installed extensions Name | Version | Schema | Description --------------------+---------+------------+------------------------------------------------------------------------ pg_prewarm | 1.2 | public | prewarm relation data pg_stat_statements | 1.11 | public | track planning and execution statistics of all SQL statements executed pgcrypto | 1.3 | public | cryptographic functions plpgsql | 1.0 | pg_catalog | PL/pgSQL procedural language (4 rows) dbtest=# select version(); version ------------------------------------------------------------------------------------------------------------------ PostgreSQL 17.2 reda build on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 13.3.0-6ubuntu2~24.04) 13.3.0, 64-bit (1 row) I'll do some additional tests.
