Re: Security Definer functions no longer works in PG14+ - Mailing list pgsql-bugs

Hi,

The aiven-extras repo has a workaround for that, using dblink: https://github.com/aiven/aiven-extras/commit/eb8c1107ca91a7da5ecb0c8127c94ce42762881d

Hello Community and Hackers,

A function like:

CREATE OR REPLACE  FUNCTION fn_sql_refresh() RETURNS void AS $$

    ALTER SUBSCRIPTION sub REFRESH PUBLICATION;

$$ LANGUAGE SQL SECURITY DEFINER;

Works with PostgreSQL 13 and older versions.

But gives error on PostgreSQL 14 as follows:

postgres=> select fn_sql_refresh();

ERROR:  ALTER SUBSCRIPTION ... REFRESH cannot be executed from a function

CONTEXT:  SQL function "fn_sql_refresh" statement 1

I believe, this is a consequence of :
https://git.postgresql.org/gitweb/?p=postgresql.git;h=ce0fdbfe9722867b7fad4d3ede9b6a6bfc51fb4e

But it is hurting good operational use cases of logical replication.
