Bug reference: 17750
Logged by: Paulo La Luna Junior
Email address: junior@rassystem.com.br
PostgreSQL version: 12.13
Operating system: Docker from image postgres:12.13
Description:

Hi,

I did several tests and the Debbuger Plugin does not work when the
shared_preload_libraries has "plugin_debugger,pg_hint_plan".
When shared_preload_libraries has only "plugin_debugger" or with other
libraries like "auto_explain,plugin_debugger,pg_stat_statements,pg_repack",
it's work.

I can create function and create extension without any error. But when I
use
Debug from PGAdmin or Dbeaver it doesn't return the debug result.

The plugin debugger uses dbg API, pg_hint_plan uses dbg API too.
Unfortunately this API is not designed to be used by two active extensions
in one time.

I found a workaround in plpgsql_check, but it requires modification in
extensions. You should report this issue to their authors.

https://github.com/EnterpriseDB/pldebugger/issues

And I see you did it.

The fix is not on the PostgreSQL side.

Pavel
