Irc channel?? / converting from Oracle

From

I tried using the #postgres channel on efnet (various servers), is that
channel very active? what times does it get traffic?? I tried sitting there
the other day and someone (a bot?) was kicking everyone after 1 minute
idle...?

I'm currently converting a system from Oracle to Postgresql, the original
design used only simple sequences/triggers (now moved across to sequences in
pgsql) with the majority of the work in java servlets. (providing web
interface) seems to be coming together nicely.

few little things I found useful.
- the syntax below works in Oracle and Postgresql

create table sample(
attrib1    varchar(20),
attrib2    numeric,                    --results in default numeric(30,6)
being generated
attrib3    numeric(5),                --results in numeric(5,0)
constraint     some_name_u_choose    primary key(attrib1),
constraint     some_name_u_choose2    foreign key table_name(attrib_name)
);

select sysdate from dual;
in Oracle gets replaced with
select current_timestamp
in Postgres. (refer the postgres manual, an excellent document!!!)

select to_char(current_timestamp, 'dd-mm-yyyy');
formats dates in dd-mm-yyyy format (or use Mon to get Jan, Feb etc)

Q: does anyone know where the standard syntax for this is defined? is this a
SQL92 standard? (I've previously picked this up from my Oracle manuals)


I'm looking at using asp, since a number of colleagues have mentioned they
find signicicent reductions in devel time... any comments? (off topic I
suspect)


so far I've had no major problems and been very impressed (installed 7.0.3
RPM on linux 6.2)

It is #postgresql, and there are usually about 14 people on it.

#postgres was a project out of University of California @ Berkeley some 5+
years ago ... as far as I know, its no longer being developed, but I could
be wrong ...

PostgreSQL is based off of that project, and ppl keep mistakenly refer to
it as such, which tends to sadly confuse new ppl :(

on efnet, its #PostgreSQL

character sets

hi all,
Does postgres support other character sets?
We've been thinking in porting an application to chinesse, but we don't
know if it's possible to store chinesse characters in postgres

TIA

I don't know what kind of Chinese are talking about, but PostgreSQL
does support both tradional Chinese and simplified Chinese.

tradional Chinese: EUC-CN

simplified Chinese: EUC-TW (you could use Big5 for clients
only. PostgreSQL will do automatic conversion between Big5 and EUC-TW,
in this case)

ALso, you could use UNICODE(UTF-8). For upcomming 7.1, PostgreSQL will
provide automatic conversion between:

UTF-8 <--> EUC-CN
UTF-8 <--> EUC-TW
UTF-8 <--> Big5

Out of interest, does --enable-recode do anything if you don't have
--enable-multibyte? I would be interested in say

  ISO8859-1 <--> ISO8859-2

but without the overhead of wide chars..

Cheers,
