Обсуждение: running PostGres without installing it

hello, how are you ?

i want to distribute a copy of PostGres to my clients.
they really dont know anything about installing
programs or
configurating remote RDBMS sql-servers,
so i dont want to give them the
"official-PostGres-installer.exe"
but my own installer.exe (win32) that:

1) install the PostGres's required files
2) modify the system as PostGres needs (registry,
paths, etc)
3) execute it as a process, not as a service (if it is
possible)
(it must run also on win98 machines)
4) enable the server in a port readed from an INI file
or
something like that.
5) delete the default super-user or change its
password
6) creates the tables-structure that my client-app
needs
7a) insert the data or
7b) copy db-files to hdd, assign them in PostGres and
make
them available via PostGres.
8) create the dbuser that will be used by clients-apps
9) assign that dbuser to my tables

all without any kind of user interaction.

- where can i get information about the required
information
(i mean: basic required files, registry changes, conf
files,
sql commands to do what i need) ?

- if this is not possible, may i call the default
PostGre's
installer in silent mode ? and if so, what are the
command-lines
to set the defaults settings ?

- can any of you help me in any of those tasks ?

thanks in advance,

I hate to say this, but maybe you should look into SQLite

Bye,

SQLite can be complied to a single binary/.dll/.so and used. That is the
route I'm looking at due to having to be an 'expert' to install
PostgresQL, and how invasive it can be on a system. I don't have any
experience with firebird or MySQL, so you might want to check out those.

SQLite goes for SQL '92 compliance whereas PostgresQL goes for I think
it is) '99 (or is it '95?) compliance.

http://sqlite.org/omitted.html tells you what is missing from the
software against the '92 standard. Against PostgresQL SQLite will lose
in the features department almost every time.

My only real issue with PostgresQL is that it is a client/server
database, that is not embeddable. If it was embeddable then I could use
it with no issue, and would in fact rather use it. I recall some people
are working on that, but don't have any links. You might want to try
www.postgresql.org and see if they any info on there.

No, there is *not* an a set of people working on "making PostgresQL
embeddable"; it has been talked about, but never taken particularly
seriously.

There's a way to do *a sort of embedding*, but one that specifically
ignores the notion of doing this in an in-process manner.

You could hide a PostgresQL instance, using a variant port, generally
making it pretty hidden away.  Initializing, starting, and stopping it
could be hidden inside the application.

But in no way would this be an embedding as is normally understood,
where all that's needful is to include a library and open the right
directory.

PostgreSQLl needs an NT like system to run on, so 98 is not an option.

It can be made to do that.
However, it should work just fine to copy the files and go from there.
You can get the binaries-no-instaler package on the web, but beware that
it does not contain all the dependencies. Another way to get the
"official version binaries" is to make an install on one machine and
then just copy everything from the directory you install it in. As of
8.1, postgresql puts *no files* in the Windows or SYSTEM32 directories.

Then you just start and stop the database using pg_ctl from inside your
app.

It's a lot more overhead than a db engine like access (JET) or sqlite,
but you do get a lot of extra features for that.
