after an unknown or failed psql backslash command, and also while
discarding "extra" arguments of a putatively valid backslash command.
In the case of an unknown/failed command, make sure we discard the
whole rest of the line, rather than trying to resume at the next
backslash. Per discussion with Thomer Gil.
There are various things left to do: contrib dbsize and oid2name modules
need work, and so does the documentation. Also someone should think about
COMMENT ON TABLESPACE and maybe RENAME TABLESPACE. Also initlocation is
dead, it just doesn't know it yet.

conversion of basic ASCII letters. Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower. These functions use the same notions of
case folding already developed for identifier case conversion. I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent. Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.
recent discussion. The lexer is used for both SQL command text and
backslash commands. The purpose of this change is to make it easier to
track the behavior of the backend's SQL lexer --- essentially identical
flex rules are now used by psql. Also, this cleans up a lot of very
squirrelly code in mainloop.c and command.c. The flex code is somewhat
bulkier than the removed code, but should be lots easier to maintain.
little more sane. Some parts of the code was using a static function
xmalloc() that did safe memory allocation (where "safe" means "bail
out on OOM"), but most of it was just invoking calloc() or malloc()
directly. Now almost everything invokes xmalloc() or xcalloc().
client-side AUTOCOMMIT mode now: '\set AUTOCOMMIT off' supports
SQL-spec commit behavior. Get rid of LO_TRANSACTION hack --- the
LO operations just work now, using libpq's ability to track the
transaction status. Add a VERBOSE variable to control verboseness
of error message display, and add a %T prompt-string code to show
current transaction-block status. Superuser state display in the
prompt string correctly follows SET SESSION AUTHORIZATION commands.
Control-C works to get out of COPY IN state.
only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON. Still TODO: provide some client-side autocommit
logic in libpq.
now, my changes seem to work. Some possible minor bugs got squished
on the way but I can't be sure without more feedback from people who
really put the code to the test.
The new patch mostly simplifies variable handling and reduces code
duplication. Changes in the command parser eliminate some redundant
variables (boolean state + depth counter), replaces some
"else if" constructs with switches, and so on. It is meant to be
applied together with my previous patch, although I hope they don't
conflict; I went back to the CVS version for this one.
One more thing I thought should perhaps be changed: an IGNOREEOF
value of n will ignore only n-1 EOFs. I didn't want to touch this
for fear of breaking existing applications, but it does seem a tad
illogical.

implementation
of '\e' history tracking for systems that have a readline compatability
library without replace_history_entry. I fall back to pushing the query
onto the history stack after the \e, rather than replacing it.
The patch adds one more place to look for readline headers, and a test
for replace_history_entry. I've only included the patch for configure.in

<blush> Even after slogging my way through the nesting #ifdefs for readline
and win32, I forgot! Let's make that a three line patch, then.
