Attached patch for unconditional enabling of pltcl-unknown support.
Enabling this feature adds very light overhead of 1 select from pg_class on
first using of pl/tcl in backend if unknown suppport is really unused.
But pl/tcl with this support has very improved functionality.
Patch includes changes to documentation.
