Yes, it seems that psql's handling of backslashes has changed for the
worse.

In current sources, I type:

regression=# select 'abc \\
regression'# def';
?column?
-----------
abc
def
(1 row)

Running with -d2, the postmaster log shows:

DEBUG: StartTransactionCommand
DEBUG: query: select 'abc
def';
DEBUG: ProcessQuery
DEBUG: CommitTransactionCommand

psql has eaten the backslashes, even though they are within quotes.
This is not cool. 6.5.* psql did not do that, and current sources
don't either *unless* the backslashes are at the very end of a line.
