(I also this question to usenet comp.databases.postgresql.novice)
I was wondering ?
Is there a way to call a function if you have it's oid or it's name, but call it indirectly ?
What I'm trying to achieve is the following :
I'd like to store a reference (the OID, or the name, since OID's can change) to an existing stored procedure in a table.
The referenced function/procedure would then be called by triggers.
Different records can point to the same procedure, and there can be a whole lot of procedures, and they will probably be in different languages, some SQL, some PGPLSQL, some C or TCL.
Is there a way to call a referenced functions ?
Or am I taking a silly approach ...
Any help, pointers to documentation, ... would be greatly appreciated.
