Hi,
I’m fairly new to postgresql and this is maybe a stupid question
(sorry beforehand): I'm trying to install
pg_stat_monitor_16-2.4.0-1PGDG.rhel9.8.x86_64 on rhel 9.8 and
postgresql 16.9.3 and I receive the message below when updating
existing version with "alter extension pg_stat_monitor update".
ERROR: could not load library "/usr/pgsql-16/lib/

This version is running fine:
pg_stat_monitor_16-2.2.0-1PGDG.rhel9.x86_64.rpm
Can someone advice?
Since the problem occurred with the pg_stat_monitor version change I
would suggest filing an issue here:
https://github.com/percona/pg_stat_monitor/issues
Especially given the below.
2.4.0
Release highlights
"This release is focused on the stability and reliability of
pg_stat_monitor. Large parts of the internals were reworked to remove
long-standing sources of crashes, memory leaks and incorrect statistics,
and the test suite was extended with test cases backported from
pg_stat_statements so that the behavior of both extensions can be
compared directly."
Add to that Ron's observation of the Postgres version being well back
from current and I think there is good case to be made for a bad
interaction between new code and old code.
Thank you.
Regards,
martin
