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

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.
