This applies, but I fail to get the expected regression test output:

Investigation shows that $::errorCode contains just "NONE", which
is why the "array set myArray $::errorCode" is blowing up.  And
that's sort of what I'd expect, because $err is
        invalid command name " spi_prepare "moo" "
which is not a Postgres-detected error.  So probably the example
tcl_error_handling_test function should not dispense with the
        if {[lindex $::errorCode 0] == "POSTGRES"}
guard that we recommend in the manual.  But I don't understand
how you got the sample output shown in the patch.  Is this based
on some unsubmitted changes in pltcl's error handling?

                        regards, tom lane
