[Message part 1 (text/plain, inline)]

I apologize for the delay,I've been off-line for a bit.  I was aware of the failure in some edge cases and I think I have a solution.  I've attached an elisp file that you should be able to require once sql.el has been loaded that overrides the function as it appears in sql.el.
Please give it a try and see if it corrects the behavior you see.
Thanks
Michael

 This bug does not happen on the 24.3 release but does happen on 24.3.93.

The problem is with sql-interactive-remove-continuation-prompt, one of
the functions configured to be called by comint-output-filter.

It is caused by code introduced by this git revision.

One workaround is to type the password in anyway. Another workaround
is to remove some of the code with the following patch:

diff --git a/lisp/progmodes/sql.el b/lisp/progmodes/sql.el
index 13d4178..2fd755d 100644
--- a/lisp/progmodes/sql.el

-
-        ;; Break up output by physical lines if we haven't hit the final prompt
-        (unless (and (not (string= oline ""))
-                    (string-match (sql-ends-with-prompt-re) oline)
-                    (>= (match-end 0) (length oline)))
-          (setq last-nl 0)
-          (while (string-match "\n" oline last-nl)
-            (setq last-nl (match-end 0)))
-          (setq sql-preoutput-hold (concat (substring oline last-nl)
-                                          sql-preoutput-hold)
-                oline (substring oline 0 last-nl))))))
+                sql-preoutput-hold "")))))
    oline)

This sql-interactive-remove-continuation-prompt function removes
continuation prompt (the prompt sent when halfway through a command)
and this improves the usability of multi-line SQL statements on the
interpreter.

There is another small bug with that code where the continuation line
sneaks through, throwing the alignment out.

By this, I mean the "template1->" prompt in the following examples:

template1=> select 42;
 ?column?
----------
      42
(1 row)

template1=> select
42;
template1->  ?column?
----------
      42
(1 row)

template1=> select
42,
43;
template1->  ?column? | ?column?
----------+----------
      42 |      43
(1 row)

That happens because of the following lines:

        ;; Add this text to what's left from the last pass
        (setq oline (concat sql-preoutput-hold oline)
              sql-preoutput-hold "")

I hope this helps.
