[GENERAL] Question about anyelement datatype
Hi I need to use the following statement in a stored procedure: EXECUTE 'SELECT * FROM ' || v_table_name INTO v_result; where v_table_name and v_result are the arguments of the function. v_table_name is of character varying type and v_result is anyelement. But as I discovered, it's not allowed to write into function arguments. I also tried to declare v_result like this: v_result v_table_name%ROWTYPE but that's not allowed either. Then I tried to use this: v_result v_data%TYPE where v_data is an argument of the same function with anyelement datatype, but no luck. Is there a way to declare such a pseudo-type variable inside the stored procedure?

[GENERAL] PostgreSQL, GnuCash
Would PostgreSQL be a good enough choise for GnuCash (or Quickbooks or the likes) type of program? What could be the potential drawbacks of using PostgreSQL (perhaps its big size)? What would be a better database for that kind of job?

Re: [GENERAL] Humor me: Postgresql vs. MySql (esp. licensing)
It's my opinion that we should be using PG, because of the full ACID support, and the license involved. A consultant my company hired before bringing me in is pushing hard for MySql, citing speed and community support, as well as ACID support. Does the consultant push "speed AND ACID" or "speed OR ACID"? My point is that PostgreSQL is said to be harder to install/maintain/tune than MySQL. I have been reading some MySQL mailing list and for what I see there, using InnoDB tables (the only way to have foreign keys, transactions, and row level locking for MySQL) makes MySQL slower and adds complexity to tuning the database. See this thread for example http://lists.mysql.com/mysql/148832 . So when someone says that PostgreSQL without tuning is 5 times slower than MySQL retrieving the same query, it is quite right to also say that MySQL InnoDB without tuning is 5 times slower than MySQL MyISAM. In my opinion you might consider MySQL only when you don't need the features provided by PostgreSQL (and even then data consistency and durability issues favor PostgreSQL) because if you need them, your developers need to implement them and do extra work, spending more time and money. It was already mentioned but I'll post this link again http://sql-info.de/mysql/ . IMHO if you are not aware of these gotchas they can also increase development time because some things are too different from regular/logical behavior (or common sense if you will) of any other database.

Re: [GENERAL] About GPL and proprietary software
That "_by whatever means_" seems to include "network link", and that doesn't sound right. Ah, but in order to use it over the network link you need to be running their server software, on the one side, and their client access software, on the other. Both sides are linked to GPL-licensed software. Your client software has to link in software belonging to MySQL AB, and that's where they are now "biting" people on this. This is one of the reasons why the PHP people removed bundled MySQL support in version 5 back in June. Would a perl application using DBI have a similar problem? Or how would one then legally use PHP with MySQL without GPL-ing your product and without buying MySQL commercial license? Kaarel
Re: [GENERAL] About GPL and proprietary software
This is neither a GNU nor a MySQL mailing list. I suggest you take your question to one of those places, as you'll get a better answer. The question in it self was more general than PostgreSQL and MySQL. However as I currently need to work with both of them I wanted to make clear the actual differences caused by licensing between the two products. The other thing is that it is probably a little easier to explain and understand if there are concrete examples. I asked this list because I didn't want to subscribe to yet another list for this matter and pgsql-general sure has the competence to answere that kind of questions. It has to have. I asked this list and not MySQL list because I am subscribed to mysql-general and comparing the two list content I like more what I see in PostgreSQL lists and the concrete example is about PostgreSQL as much as it is MySQL. I don't think at a PostgreSQ conference you would guide me to MySQL conference when I asked this same question would you? Licensing is quite difficult to understad (at least for me) yet a very important aspect of software development. I don't intend to ruine anybodys day I just want a small discussion which in the end would explain the cases when the licensing aspect of these two concrete products will play an important role in developing software.
