Repair problem noted by Elphick: make_rels_by_joins failed to handle
cases where joinclauses were present but some joins have to be made
by cartesian-product join anyway. An example is
SELECT * FROM a,b,c WHERE (a.f1 + b.f2 + c.f3) = 0;
Even though all the rels have joinclauses, we must join two of them
in cartesian style before we can use the join clause...

On HPUX, shl_load should be called with options BIND_IMMEDIATE rather
than BIND_DEFERRED. That way, if the loaded library has unresolved
references, shl_load fails cleanly. As we had it, shl_load would
succeed and then the dynlinker would call abort() when we try to call
into the loaded library. abort()ing a backend is uncool.

Remove broken tracing code (which would be dangerous if it did work...)
libpq++.h contained copies of the class declarations in the other libpq++
include files, which was bogus enough, but the declarations were not
completely in step with the real declarations. Remove these in favor
of including the headers with #include. Make PgConnection destructor
virtual (not absolutely necessary, but seems like a real good idea
considering the number of subclasses derived from it). Give all classes
declared private copy constructors and assignment operators, to prevent
compiler from thinking it can copy these objects safely.

pltcl didn't work well at all when Tcl had been built with a different
