There is an option "-s oldname=newname", which changes the old field name of
the dbf-file to the newname in PostgeSQL. If the length of the new name is 0,
the field is skiped. If you want to skip the first field of the dbf-file,
you get the wildest error-messages from the backend.
dbf2pg load the dbf-file via "COPY tablename FROM STDIN". If you skip the
first field, it is an \t to much in STDIN.
A fix could be an counter j=0, which increments only, if a field is imported
(IF (strlen(fields[h].db_name)> 0) j++. And only if j > 1 (if an other field is
imported) the \t is printed.
An other small bug in the README:
-s start
Specify the first record-number in the xBase-file
we will insert.
should be
-e start
Specify the first record-number in the xBase-file
we will insert.

the new timetravel.c,
new timetravel.README (cut from spi/README and modified),
modified timetravel.sql.in
and modified timetravel.example.
Features:
- optionally 3 parameter for insert/update/delete user name
- work with CREATE UNIQUE INDEX ixxx on table xxx
(unique_field,time_off);
(the original version was work with unique index on 6.5.0-6.5.3,
and not work on 7.3.2,7.3.3)
(before 6.5.0 and between 6.5.3 and 7.3.2 I dont know)
- get_timetravel(tablename) function for check timetravel-status.
- timetravel trigger not change oid of the active record. (it is not a
good feature, because the old version is automatice prevent the paralel
update with "where oid=nnn")

- Quick cleanup of analyze.c function prototypes.
- New non-reserved keywords (INCLUDING, EXCLUDING, DEFAULTS), SQL 200X
Opted not to extend for check constraints at this time.

slave
servers. I haven't tested it very well, so use at your own risk (and I
recommend against using it in production).
Basically, I have a central database server that has 4 summary tables
inside
it replicated to a remote slave (these database tables are for my mail
server
authentication, so these are replicated to another server tuned for many
connections, and so I don't have postgres connections opened straight to
my
back-end database server).
Unfortunately, I also wanted to implement a replication database server
for
hot-backups. I realized, too late, that the replication process is
pretty
greedy and will try to replicate all tables marked as a
"MasterAddTable".
To make a long story, I made a patch to RServ.pm and Replicate that
allows you
to specify, on the command line, a list of tables that you want to
replicate...it'll ignore all others.
I haven't finished, since this has to be integrated with CleanLog for
instance, but this should (and does) suffice for the moment.
I have yet to test it with two slaves, but at least my mail server
replication
database now works (it was failing every time it tried to replicate, for
a
variety of reasons).
Anyone have any suggestions on how to improve on this? (or, if someone
more
familiar with this code wants to take the ball and run with it, you're
welcome to).

Nice catch.
There was a bug in the original metaphone algorithm from CPAN. Patch
attached (while I was at it I updated my email address, changed the
copyright to PGDG, and removed an unnecessary palloc). Here's how it
looks now:
regression=# select metaphone(a,4) from (select 'A A COMEAUX
MEMORIAL'::varchar AS a) a;
metaphone
-----------
AKMK
(1 row)
regression=# select metaphone(a,5) from (select 'A A COMEAUX
MEMORIAL'::varchar AS a) a;
metaphone
-----------
AKMKS
(1 row)

Also quickly added mention that it may be a qualified schema name.

Add "-l $PGLOG" for restart --- Darko Prenosil

* A few bug fixes
* fixes solaris compile and crash issue
* decouple vacuum analyze and analyze thresholds
* detach from tty (dameonize)
* improved logging layout
* more conservative default configuration
* improved, expanded and updated README
please apply and 1st convenience, or before code freeze which ever comes
first :-)
At this point I think I have brought pg_autovacuum and its client side
design as far as I think it should go. It works, keeping file sizes in
check, helps performance and give the administrator a fair amount
flexibility in configuring it.
Next up is to do the FSM based design that is integrated into the back
end.
p.s. Thanks to Christopher Browne for his help.

1 intarray: bugfix for int[]-int[] operation
2 intarray: split _int.c to several files (_int.c now is unused)
3 ntarray (gist__intbig_ops opclass): use special type for index storage
4 ltree (gist__ltree_ops opclass), intarray (gist__intbig_ops): optimize
GiST's
penalty and picksplit interface functions, now use Hemming distance.

Add support for PGHOST, PGPORT, PGUSER environment variables

yy_fatal_error() call results in elog(ERROR) not exit(). This was
already fixed in the main lexer and plpgsql, but extend same technique
to all the other dot-l files. Also, on review of the possible calls
to yy_fatal_error(), it seems safe to use elog(ERROR) not elog(FATAL).

of an index can now be a computed expression instead of a simple variable.
Restrictions on expressions are the same as for predicates (only immutable
functions, no sub-selects). This fixes problems recently introduced with
inlining SQL functions, because the inlining transformation is applied to
both expression trees so the planner can still match them up. Along the
way, improve efficiency of handling index predicates (both predicates and
index expressions are now cached by the relcache) and fix 7.3 oversight
that didn't record dependencies of predicate expressions.

docs that CLIENT/LOG_MIN_MESSAGES now controls debug_* output location.

blanks, in hopes of reducing the surprise factor for newbies. Remove
redundant operators for VARCHAR (it depends wholly on TEXT operations now).
Clean up resolution of ambiguous operators/functions to avoid surprising
choices for domains: domains are treated as equivalent to their base types
and binary-coercibility is no longer considered a preference item when
choosing among multiple operators/functions. IsBinaryCoercible now correctly
reflects the notion that you need *only* relabel the type to get from type
A to type B: that is, a domain is binary-coercible to its base type, but
not vice versa. Various marginal cleanup, including merging the essentially
duplicate resolution code in parse_func.c and parse_oper.c. Improve opr_sanity
regression test to understand about binary compatibility (using pg_cast),
and fix a couple of small errors in the catalogs revealed thereby.
Restructure "special operator" handling to fetch operators via index opclasses
rather than hardwiring assumptions about names (cleans up the pattern_ops
stuff a little).
