Thread: pgsql: In PL/Tcl, make database errors return additional info in the er

In PL/Tcl, make database errors return additional info in the errorCode.

Tcl has a convention for returning additional info about an error in a
global variable named errorCode.  Up to now PL/Tcl has ignored that,
but this patch causes database errors caught by PL/Tcl to fill in
errorCode with useful information from the ErrorData struct.
