Case Studio?

Sorry, I should have also specified that we are looking for a tool where we
can save the schema externally. Then take that schema and have the tool
compare it to a database and generate a change script.

So the process would be to maintain database structure in a tool.
Be able to save the schema.
Then have the tool compare the schema to an existing database and generate a
SQL change script to update the database model.

I am not an expert user of pgadmin, but my understanding is that it lets you
maintain a particular database, but does not have facilities for comparing
schemas and generating change scripts, etc.

For example, this tool doesn’t realize that in postgres you can’t add a
column and set not null in one ALTER TABLE statement.  So we are forced to
manually comb through the SQL scripts it creates and fix the buggy
statements.
 
So my question is, postgres general newsgroup, what database modelling tools

Thank you,

Says it supports PostgreSQL:

I use ER/Win for everything, but it is very pricey and it does not
support PostgreSQL directly (only indirectly via ODBC).

Postgres Newsgroup,

My company has been looking for a good database modelling tool for
postgres and have yet to find something that completely satisfies our
needs. We are currently using a product called DBWrench which is pretty
good and has all the features we are looking for but is full of bugs and
creates much head ache.

For example, this tool doesn't realize that in postgres you can't add a
column and set not null in one ALTER TABLE statement. So we are forced
to manually comb through the SQL scripts it creates and fix the buggy
statements.

So my question is, postgres general newsgroup, what database modelling
tools do you use? Open source or commercial it doesn't matter to me.

Thank you,

Mark

This is my fav....its just awesome...

I have to say that ERwin is pretty much the bomb. It indirectly
supports postgresql through ODBC, which I've used with much success.
It will also port your schema to another RDBMS system if you wish. It
can build a model from either a running database or DDL or by
construction, and will also output to all of the above. Very
excellent tool, but I think it's about $4k/license. Is it worth it?
hell yeah.

Case Studio doesn't generate alter statements.
It does have a database comparison tool, which I have found to be very cool.

I love Case Studio (www.casestudio.com). It's inexpensive,
well-supported, easy to use. Problem is that it doesn't do the DDL diff
that he wants. I was looking for exactly the same feature/tool last
year to build update scripts for client schemas.

For example, this tool doesn't realize that in postgres you can't add a
column and set not null in one ALTER TABLE statement. So we are forced to
manually comb through the SQL scripts it creates and fix the buggy
statements.

AFAIK started from version 8 it can be combined into single alter statement.

speaking of visual tools - does anyone know a tool to "pretty" SQL
statement (ala "tidy")? Sometimes we have to dig thruogh
auto-generated SQL queries 30k-60k size, which is quite hard to do
when it's one row w/o any indents and line breaks.

Do you know if this program will do forward-engineering.

I would like to be able to take a copy of my live database.
Reverse engineer it into SQLManager, modify it.

Then forward-engineer, do you know if SQLManager allows me to do that?
