Per discussion in [1], this patch improves error reporting in pltcl.

I forgot to mention that this work is sponsored by Flight Aware

Huh ... I use that site.  There's PG and pltcl code behind it?
Cool!

I didn't study this patch deeper yet. Just I am sending rebased code

I found one issue. The context

+ ERROR:  relation "foo" does not exist
+ CONTEXT:  relation "foo" does not exist
+     while executing
+ "spi_exec "select * from foo;""
+     ("eval" body line 1)
+     invoked from within
+ "eval $1"
+     (procedure "__PLTcl_proc_16461" line 3)
+     invoked from within
+ "__PLTcl_proc_16461 {spi_exec "select * from foo;"}"
+ in PL/Tcl function "tcl_eval"

is changed in any call - when I did "make installcheck"

*** 567,575 ****
      ("eval" body line 1)
      invoked from within
  "eval $1"

  in PL/Tcl function "tcl_eval"
  select pg_temp.tcl_eval($$
  set list [lindex $::errorCode 0];

I am not able to see, if this information is interesting or not. We can hide context, but I have not a idea, if it is ok or not.
