initial response is 'S', not 'Y', when it is willing to do SSL.

via extended query protocol, because it sends Sync right after Execute
without realizing that the command to be executed is COPY. There seems
to be no reasonable way for it to realize that, either, so the best fix
seems to be to make the backend ignore Sync during copy-in mode. Bit of
a wart on the protocol, but little alternative. Also, libpq must send
another Sync after terminating the COPY, if the command was issued via
Execute.

Per yesterday's discussion, this offers enough performance improvement
to justify bending the 'no new features during beta' rule.

heuristic determination of day vs month in date/time input. Add the
ability to specify that input is interpreted as yy-mm-dd order (which
formerly worked, but only for yy greater than 31). DateStyle's input
component now has the preferred spellings DMY, MDY, or YMD; the older
keywords European and US are now aliases for the first two of these.
Per recent discussions on pgsql-general.

>>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.

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

modes (and replace the requiressl boolean). The four options were first
spelled out by Magnus Hagander <mha@sollentuna.net> on 2000-08-23 in email
to pgsql-hackers, archived here:
http://archives.postgresql.org/pgsql-hackers/2000-08/msg00639.php
My original less-flexible patch and the ensuing thread are archived at:
http://dbforums.com/t623845.html
Attached is a new patch, including documentation.
To sum up, there's a new client parameter "sslmode" and environment
variable "PGSSLMODE", with these options:
sslmode description
------- -----------
disable Unencrypted non-SSL only
allow Negotiate, prefer non-SSL
prefer Negotiate, prefer SSL (default)
require Require SSL
The only change to the server is a new pg_hba.conf line type,
"hostnossl", for specifying connections that are not allowed to use SSL
(for example, to prevent servers on a local network from accidentally
using SSL and wasting cycles). Thus the 3 pg_hba.conf line types are:
pg_hba.conf line types
----------------------
host applies to either SSL or regular connections
hostssl applies only to SSL connections
hostnossl applies only to regular connections
These client and server options, the postgresql.conf ssl = false option,
and finally the possibility of compiling with no SSL support at all,
make quite a range of combinations to test. I threw together a test
script to try many of them out. It's in a separate tarball with its
config files, a patch to psql so it'll announce SSL connections even in
absence of a tty, and the test output. The test is especially informative
when run on the same tty the postmaster was started on, so the FATAL:
errors during negotiation are interleaved with the psql client output.
I saw Tom write that new submissions for 7.4 have to be in before midnight
local time, and since I'm on the east coast in the US, this just makes it
in before the bell. :)

Along the way, fix some logic problems in pgstat_initstats, notably the
bogus assumption that malloc returns zeroed memory.

Attached documentation patch updates the wording for bytea input
escaping, per complaint by Stephen Norris above.

for the sign of timezone offsets, ie, positive is east from UTC. These
were previously out of step with other operations that accept or show
timezones, such as I/O of timestamptz values.
