Обсуждение: Is pl/pgsql debugging broken in PostgreSQL 9.0, or is it just me?

Hi folks,

I had the debugger working in pgAdminIII at one point, some time
before upgrading to 9.0, but as of right now I can't seem to get it
working using the usual steps. I believe it may have something to do
with the DLL not loading correctly, because the following query:

LOAD '$libdir/plugins/plugin_debugger.dll';
show shared_preload_libraries;

...returns a blank row. The DLL is present, and if I change the load
string, it complains, so I'm pretty sure it's finding the DLL okay,
but not successfully loading it. show local_preload_libraries returns
the same thing.

Any ideas?

Thanks,
Kev

LOADing the DLL won't make it show up there - you need to modify that
config directive in postgresql.conf

Never mind, I had been selecting non-plpgsql functions.  :#

Sorry about that.  Thanks for your time and patience.

Oops!  So...I added this to postgresql.conf:

shared_preload_libraries = '$libdir/plugins/plugin_debugger.dll'        #
(change requires restart)

...and restarted.  Now "show shared_preload_libraries" returns
"$libdir/plugins/plugin_debugger.dll", but the debugging options are
still greyed out in pgAdminIII.  All of the pldbg_* functions exist in
the schema I'm looking at.  What's next?

Thanks,
Kev
