Обсуждение: ntfs for windows port rc5-2
why? since an app that I'm working on would be useless for 60% of potential clients, using posgresql with the requirement for ms' corrupted ntfs means postgresql isn't going to work for it. since ms does not include a compiler, and the source for 8.0 won't cross compile from linux. ( gcc 3.3.0 ) whatever happened to targeting lowest common denominator, instead of highest?

Hi, Does anyone know if there is a way to get the backends IP address from the PID? I am using the view pg_stat_activity and it would be nice if it would also display the IP address along with the PID. I can see the IP address when I do a ps -ef but it would be nice to be able to get it via a sql command. Thanks, Tony Caduto http://www.amsoftwaredesign.com

I don't think that Windows isn't worth using some versions such as XP are quite
stable for most purposes. By no means am I saying go put a production database
server like Postgres or Oracle on it. SMB's (Small - to - Medium Businesses) may
benefit from Windows 2000 if there aren't able to get somebody who can manage
Linux/Unix in their environment and don't have a heavy load.
Cheers,
Aly.

Do you mean the IP address of the backend (the server) or the address
of the client that's using that backend?
PostgreSQL 8.0 will have inet_client_addr() and inet_server_addr()
functions to get the client and backend IP addresses for the current
session, but I'm not aware of a way to get another session's IP
addresses via an SQL query.

That probably wouldn't be hard to add -- consider submitting a patch
or suggesting it to the developers.

A workaround would be to write a function that runs ps, netstat,
lsof, etc., and extracts the IP address from the command's output.
Here's a set-returning plperlu example that works with PostgreSQL
8.0.0rc5 on FreeBSD 4.11:
CREATE TYPE pid_ip AS (
pid integer,
ipaddr inet
);
CREATE FUNCTION backend_client_ips() RETURNS SETOF pid_ip AS $$
my $psprog = "/bin/ps";
my $rows;
if (open(my $ps, "-|", $psprog, $pid)) {
while (<$ps>) {
if (/^\s*(\d+).*postmaster: \S+ \S+ (\d+\.\d+\.\d+\.\d+)/) {
push @$rows, {pid => $1, ipaddr => $2};
}
}
close $ps;
} else {
elog ERROR, "$psprog: $!";
}
return $rows;
$$ LANGUAGE plperlu VOLATILE;
SELECT * FROM backend_client_ips();
pid | ipaddr
-------+-----------
78563 | 10.1.0.1

This is a different thing. We don't support 9x for a *lot* of reasons. The lack of NTFS is a very minor one. There are a *lot* of other things that are just not inmplemented, or so badly implemented it's unusable, in these systems. Your only option in this case is the Cygwin version, where a huge amount of work has gone into re-implementing these things in teh Cygwin framework. AFAIK it works on 9x - as well as anything can ;-) >since the app will not be world accessable, only through >localhost, the >lack of security isn't a major concern.

Ok. There is indeed a bug here. Seems this codepath is not exercised a lot - most people follow the advice not to store their data on FAT ;-) And the other tests just exercised the case when you didn't do a service install at all. The pgperm.bat file incorrectly tries to do cacls on the DATA directory even if it's installed on FAT. It correctly skips the bin, lib, share etc paths, but not DATA. Dave has committed a fix for this and it will be in the release. //Magnus

Yes, I updated the TODO:
* Add the client IP address to pg_stat_activity
and while there is a client version that does your connection, it
doesn't work for other connections.
I think we should display all the info we show in ps -ef in
pg_stat_activity and the one piece we don't give currently is the client
address.

Bruce, On another note, is there plans to improve the type checking of stored functions during the save/compile? Currently I can pretty much make tons of mistakes (on purpose of course :-) and they are not flagged as errors until runtime. The biggest complaint I see from other DBAs (MS SQL, Oracle) is that Postgres does little to no pre-runtime type checking.

I have hit this as well though unlike Tony my errors are generally not test cases! If for example you mistype a column/variable name inside the function Postgres will create and allow the function to run as long as the path through the function containing the error is not executed. It would be nice to be told about the error on function creation/modification. Although I feel this is almost a feature as it keeps me honest and testing every possible path through my functions a little bit more thoroughly than I might have been doing with Oracle and MSSQL.... It would still be nice to have some idiotproofing. Is there info on what the check_function_bodies does check?

Good point, added:
* Add the client IP address and port to pg_stat_activity
and yes, it would support IPv6.
