[GENERAL] sequences and dependences
Hi, I would like to write a request where I would get the table name and column name of a sequence. In fact I want the opposite of pg_get_serial_sequence ! I have been looking at the sytem table and could not link the sequence from pg_class to a table (and even less to a table). And I have not been sucessful looking at the net either !

Re: [GENERAL] XML Support related questions
Am Donnerstag, 22. Mai 2008 schrieb Brijesh Shrivastav: 1) Can xml column be constrained to be DOCUMENT or CONTENT type? Using a check constraint that does IS [NOT] DOCUMENT on the value. 2) Is there plan in near future to support XML schema validation i.e to ensure inserted xml document conforms to a preregistered set of XML schemas. Plans yes, but I don't think anyone is working on it at the moment. 3) Support for XQuery - I know it is asking for too much but when do you see it happening in the future. See #2. 4) Support for xml indexes - Is it something that is being worked upon for next release? See #3. ;-) Of course this question is a bit underspecified, because indexes depend on some operators, and XML does not have any operators at the moment, so what do you want to index? -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] sequences and dependences
I would like to write a request where I would get the table name and column name of a sequence. In fact I want the opposite of pg_get_serial_sequence ! You are looking for refobjid in pg_depend, but this time the sequence could be a dependent to more than table. A query like the one bellow is should give you the name of the table, assuming you account for the correct namespace; it will not automatically show the name of the column: select objid::regclass, refobjid::regclass from pg_depend where objid::regclass::text = 'person_id_seq' ; Thanks Ioannis Tambouras -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] SUMMARY: Solaved. apache perl cgi script cant load libpq.5.dylib on mac os tiger
Hmmm,
It was the protection on the /usr/local/pgsql directory. Solved, by myself
an hour after making this post. Odd that, its been bugging the heck out of
me for over a week now, and then one hour after posting

I have a perl cgi script that wont run on a new mac. The script runs fine
from the command line, so the perl and postgresql seem good. However
when run as an apache cgi script the postgresql stuff fails as shown

The script is not using mod perl. It is using the apple os x 10.4.11 supplied
version of apache, postgresql-8.3.0 and perl, v5.8.8 with DBD::Pg, DBI and
JSON installed.
I am at a total loss as to why the library cant be found and would be
very grateful for any help.

[GENERAL] editing functions/triggers etc..
Hi, I was wondering if anyone has written a tool that will drop (cascade) then allow the edit and then restore the functions/triggers including the adding the function/triggers to the inserts/deletes/etc.. to the tables. It turns out that have to change 50 fifty triggers. At the moment I create a list of the tables -remove the link, edit the code, restore the link. This is not working very well.

[GENERAL] Optimzing Postgresql
Hi, I am deciding between MySQL and Postgres. I'm leaning towards Postgres mainly due the widely publicized speed when using transactions. However, I am not able to find any good books / resources for tuning/ optimizing the database. Is there a book like High Performance MySQL for Postgres that teaches what the different parameters are and how to tune them? Or do most techniques covered in the High Performance Mysql apply to Postgres too? Thanks, Ram

The postgresql manual is good. http://www.westnet.com/~gsmith/content/postgresql/pg-5minute.htm is a five minute tuning overview. http://www.powerpostgresql.com/PerfList/ is a good overview of basic tuning, written for 8.0 but still pretty applicable. Hang out on the pgsql-performance mailing list and see what other people do - How do I tune a database for X comes up pretty regularly, and gets good answers, so trolling through the mailing list archive can give some very good advice. Or do most techniques covered in the High Performance Mysql apply to Postgres too? Probably not. Mysql has a very different philosophy to postgresql. And some approaches that are suggested to work around performance issue on mysql may actually harm performance on other databases.

There's no book, that I know, dedicated to tuning PostgreSQL performance, but the PostgreSQL book by Korry Douglas has a big section on tuning and statistics gathering: http://www.amazon.com/PostgreSQL-Developers-Library-Korry-Douglas/dp/0672327562 There are plenty of overlaps between tuning PostgreSQL and tuning any other database, such as using the right RAID setup to optimize I/O. PostgreSQL has a bunch of parameters for controlling buffer sizes, write-ahead logging, sort memory and so on. Here's a decent overview: http://www.powerpostgresql.com/PerfList When looking for material, make sure it's updated to the 8.x series, which drastically changed the way PostgreSQL manages its cache buffers.
