Fix psql history handling:
> 1) Fix the problems with the \s command. > When the saveHistory is executed by the \s command we must not do the > conversion \n -> \x01 (per > http://archives.postgresql.org/pgsql-hackers/2006-03/msg00317.php ) > > 2) Fix the handling of Ctrl+C > > Now when you do > wsdb=# select 'your long query here ' > wsdb-# > and press afterwards the CtrlC the line "select 'your long query here '" > will be in the history > > (partly per > http://archives.postgresql.org/pgsql-hackers/2006-03/msg00297.php ) > > 3) Fix the handling of commands with not closed brackets, quotes, double > quotes. (now those commands are not splitted in parts...) > > 4) Fix the behaviour when SINGLELINE mode is used. (before it was almost > broken ;( Sergey E. Koposov
