Hello Christopher, > [...] > Please could you encourage them to do this, or perhaps do it yourself? > You seem to have a good knowledge of English. > [...] I will see, if I can encourage Addison Wesley to translate the book. Regarding the translation on my own - thank you very much for your compliment ;-) Unfortunately my knowledge of the english language does not go as far as it seems to do ... much of it costs me valuable time to look up the right words. Therefore I do not really think about a translation by myself ... you would surely repent it :-) Best regards, Jens - T-Systems Projektleiter debis Systemhaus GEI GmbH Hausanschrift: Eichhornstraße 3, 10785 Berlin Postanschrift: 10785 Berlin Telefon: (004930) 25 54-32 82 Telefax: (004930) 25 54-31 87 Mobiltelefon: (0170) 167 26 48 E-Mail: [EMAIL PROTECTED] Internet: http://www.t-systems.de
AW: [GENERAL] Addison-Wesley looking for authors
Hello all, hello Bruce, first of all I want to say, that Bruces Book was very well done in my opinion! To answer the question, I already began writing a book about PostgreSQL for Addison Wesley in Germany. It will be released in autumn this year in german language. Perhaps it could be translated by Addison Wesley Corp.? My book does not try to compete with Bruces book (I wouldnt dare to do ;->), it rather does complete the theme while it will contain many, many examples from real life (besides many small examples, the whole book is accompanied by one constantly growing example) and it will contain a rather complex section about PL/pgSQL-programming and application development, also accompanied by many examples. At least I would like to thank Bruce for the offered help - I surely will remember ;-) Best regards, Jens Hartwig - T-Systems Projektleiter debis Systemhaus GEI GmbH Hausanschrift: Eichhornstra?e 3, 10785 Berlin Postanschrift: 10785 Berlin Telefon: (004930) 25 54-32 82 Telefax: (004930) 25 54-31 87 Mobiltelefon: (0170) 167 26 48 E-Mail: [EMAIL PROTECTED] Internet: http://www.t-systems.de > -Ursprungliche Nachricht- > Von: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]Im Auftrag von > Bruce Momjian > Gesendet: Dienstag, 27.

Re: [GENERAL] How I can join between the other database's tables?
Hello all, I think you are both right. The one says that tables which are related enough to be joined should stay in one database and the other says that it could be necessary for many reasons to hold the tables in different databases. Even if I never was in need to join tables from different databases (in this point I agree with Adam Haberlach), we have many applications which use separate databases for lookup-queries or for the sake of synchronization or replication of databases, therefore I absolutely agree with Adam Rossi. In fact, I also would be very content if PostgreSQL would be enabled to work with different databases (perhaps in some future release?).

Re: [GENERAL] User Privileges
Hello, the information can be found in the system-table-column PG_CLASS.RELACL: SELECT RELACL FROM PG_CLASS WHERE RELNAME = 't_dummy'; The result seems to be an array of granted permissions, so you should treat it is an array and look for the appropriate user- or group-name.

Re: [GENERAL] deletion of records before commit doesn't work
Hello all,
I just reproduced the same phenomenon on my installation (PostgreSQL
7.0.2 on i686-pc-linux-gnu, compiled by gcc egcs-2.91.66) and it seems
to me that maybe the index is not correctly actualized while inserting
the record? It seems that any (!) update on blah (before executing the
delete) will solve the problem:
...
insert into blah (subdiv_code) values ('VG');
delete from blah where subdiv_code='VG';
...
=> ERROR
...
insert into blah (subdiv_code) values ('VG');
update blah set subdiv_code='VG' where subdiv_code='VG';
delete from blah where subdiv_code='VG';
...
=> OK
...
insert into blah (subdiv_code) values ('VG');
update blah set subdiv_code=subdiv_code;
delete from blah where subdiv_code='VG';
...
=> OK
...
insert into blah (subdiv_code) values ('VG');
update blah set id=id;
delete from blah where subdiv_code='VG';
...
=> OK
Best regards, Jens

[GENERAL] Damaged table "pg_access"
Hello all, when I try to access the system-table "pg_class", I get the following error: zeda=# select * from pg_class; NOTICE: get_groname: group 1 not found pqReadData() -- backend closed the channel unexpectedly.

Is there any way to repare the damaged table? Thanks in advance for all of you, who spend their valuable time!
