Pavel,
What do you think you need for enhanced protocol ?

We can write debugger with breakpoints without bytecode. Every stmt
rec
can have flag if has breakpoints. No problem. I don't see any
advance of
bytecode. Maybe, goto stmt is possible.
What is problem? We need synchronous comunication (message) between
backend frontend.
I have idea (in exec_stmt()
CHECK_FOR_INTERRUPTS();
if (stmt->breakpoints)
estate->debug_mode = true;
if (estate->debug_mode)
{
for (;;)
{
rc = request_command();
switch (rc)
{
case 'c': -- continue
estate->debug_mode = false;
break
case 'q':
elog(EXCEPTION, "stop debug");
break;
case 'n':
break;
case 'l':
sendstring(line(estate->src,
stmt->lineno));
Please, can somebody help me with protocol enhancing? It is mayor
work on
PL/pgSQL debugger (and plperl and plpython too).
Using a java jvm however is considerable overkill.

I don't recommend discussion for this in this thread, but it could
also tie in with the packages support we've discussed and
(although some may argue this), compiling the PL to bytecode and
using that.
How would compilation to bytecode help?
