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.

we were "in flight" to it.  This is not a significant problem when the root
is above the leaf level, but if the root was also a leaf (ie, a single-page
index just got split) we may return the wrong leaf page to the caller,
resulting in failure to find a key that is in fact present.  Bug has existed
at least since 7.1, probably forever.

internal errors.

I'd have to disagree with regards to the memory leaks not being worth
a mention - any such leak can cause problems when the PostgreSQL
installation is either unattended, long-living andor has very high
connection levels. Half a kilobyte on start-up isn't negligible in
this light.

the bulk of the heavy lifting ...

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")

>>ISTM that "source" is worth knowing.

> Hm, possibly.  Any other opinions?

This version has the seven fields I proposed, including "source". Here's
an example that shows why I think it's valuable:

regression=# \x
Expanded display is on.
regression=# select * from pg_settings where name = 'enable_seqscan';
-[ RECORD 1 ]-----------
name    | enable_seqscan
setting | on
context | user
vartype | bool
source  | default
min_val |
max_val |

regression=# update pg_settings set setting = 'off' where name =
'enable_seqscan';
-[ RECORD 1 ]---
set_config | off

regression=# select * from pg_settings where name = 'enable_seqscan';
-[ RECORD 1 ]-----------
name    | enable_seqscan
setting | off
context | user
vartype | bool
source  | session
min_val |
max_val |

regression=# alter user postgres set enable_seqscan to 'off';
ALTER USER

(log out and then back in again)

regression=# \x
Expanded display is on.
regression=# select * from pg_settings where name = 'enable_seqscan';
-[ RECORD 1 ]-----------
name    | enable_seqscan
setting | off
context | user
vartype | bool
source  | user
min_val |
max_val |

In the first case, enable_seqscan is set to its default value. After
setting it to off, it is obvious that the value has been changed for the
session only. In the third case, you can see that the value has been set
specifically for the user.

annoyed me the other day while I was documenting my current project. It
makes pg_dump use the same layout for types as for tables, by putting "\n\t"
before the first field and "\n" before the final ");"

Can't really justify this too much except to say I had an itch and I
scratched it ;-)

  psql4win32.patch  - changes in the psql source code
  psql-ref.patch    - changes in the documentation psql-ref.sgml
                      (for new builtin variable WIN32_CONSOLE)

To apply them use "patch -p 1" in the root directory of the
postgres source directory.

These patches fix the following problems of psql on Win32
(all changes only have effect #ifdef WIN32):

  a) Problem:  Static library libpq.a did not work
     Solution: Added WSAStartup() in fe-connect.c

  b) Problem:  Secret Password was echoed by psql
     Solution: Password echoing disabled in sprompt.c

  c) Problem:  8bit characters were displayed/interpreted wrong in psql
               This is due to the fact that the Win32 "console" uses a
               different encoding than the rest of the Windows system
     Solution: Introduced a new psql variable WIN32_CONSOLE
               When set with "\set WIN32_console", the function OemToChar()
               is applied after reading input and CharToOem() before
               displaying Output

that the regression tests for foreign keys didn't seem to test
a deferred constraint that was not satisified by a later
statement and was not made immediate by set constraints,
so here's a simple added test with a single invalid insert and
a commit.

OK; the only change in this version is "isconst = false;". Now you can
use $0 as a result placeholder if desired. E.g.:

create or replace function tmp(anyelement, anyelement) returns anyarray as '
declare
  v_ret alias for $0;
  v_el1 alias for $1;
  v_el2 alias for $2;
begin
  v_ret := ARRAY[v_el1, v_el2];
  return v_ret;
end;
' language 'plpgsql';

create table f(f1 text, f2 text, f3 int, f4 int);
insert into f values ('a','b',1,2);
insert into f values ('z','x',3,4);

select tmp(f1,f2) from f;
select tmp(f3,f4) from f;
