Error message with plpgsql CONTINUE

Calling CONTINUE with a label that's not a loop produces an error 
message with no context info [1]. This is because of
rc = exec_stmt_block(&estate, func->action);if (rc != PLPGSQL_RC_RETURN){    estate.err_stmt = NULL;    estate.err_text
=NULL;
 

I trawled through git blame a bit and it looks like it's been that way 
for a very long time.

I think err_stmt should probably only be reset in the non-return case a 
bit below that. I'm not sure about err_text though. Also, the code 
treats PLPGSQL_RC_OK and PLPGSQL_RC_EXIT the same, which seems like a 
bug; I would think PLPGSQL_RC_EXIT should be handled the same way as 
CONTINUE.

If someone can confirm this and tell me what to do about err_text I'll 
submit a patch.
