    Um - and that's the only unresolved one?

    Which  version  of Tcl is used from PL/Tcl, and which version
    is the Ldap.so linked against?

    Kinda that is on my personal TODO/wishlist. Splitting  PL/Tcl
    into  two  separate  interpreters  internally,  identified by
    different language names.  The  unsafe  language,  with  full
    access to OS under the postgres userID, would be an untrusted
    language, so  creation  of  functions  is  restricted  to  DB
    superusers.
