Sorry Martin,
your help is wanted, I'm just fully into geting xdb_sql for oracle runing under Debian, and preparing myself for the 'Linux Tag 2004'.
I got moste critical Bugs out of nsjabber/jabber package for postgres , and I included your jabber-drop.sql into the package (thanks 😊 ). I will set up an installation at www.theservice.de/jabber the next days , so every one can test it.
We probarbly having a Forum there to discuss further development, as well.
Regarding the function/procedure problem:
You are able to put one SELECT (postgres) statement into a db_exec_plsql call, if you need to call more than one function you have to wrap them into a BEGIN ... END; Block.
I will upload all changes to the file storage after the 'Linux Tag' (next weekend).
Cheers
