Postgresql doesn't need any client dll?

By looking at
http://www.devart.com/unidac/
on PostgreSQL there is a "direct" connection to unidac,

does this mean that an application made with UniDac and PostgreSQL provider will work on a fresh installation of Windows without the need of installing any client library (like for example it is needed for Firebird)?

If this is true I have to consider supporting PostreSQL instead of Firebird.

I've been using UniDAC with both SQL Server and PostgreSQL and not added any additional drivers for Pg.

I was actually going to use FB too but have gone with Pg

Hello

PgDAC and UniDAC with PostgreSQL provider can connect to PostgreSQL database without any client DLL's.

If you are interested in working with PostgreSQL database without client DLL's then you can download the trial version and test it.

Thanks to both. So very good news, this is a plus of Postgresql vs firebird.

One note: MS SQL server works without dll is not really true, it works because the native client is installed in every windows machine...

I finally was able to build a sample Postgresql application.

I wanted to test the no-need-of-dll so I tried to run the exe from another machine but I have this message:

"
UniDAC Trial version needs additional "bpl" files to be present on the user PC.
If you build your project without run-time packages you need:
dac120.bpl
unidac120.bpl
"

I fon't have those files, it is not possible so with the trial run the exe on a mahcine that doesn't have unidac installed?

Moreover: is it possible to upgrade from SDAC to UNIDAC or UNIDAC is a totally different product. I mean are there upgrade policies (=discounts)?

Thanks.

I'm pretty sure the first time I used the demo version, I had those files and was able to put them on another test PC whilst I tried my test application on the other PC.
Are you sure you don't have them in the windows\system32 folder
or under the UniDAC folders? (possibly your Delphi bpl folder)

When you buy the release version you won't need to distribute these, it is only the demo version that requires them.

It is a trial limitation of UniDAC to use the following bpl's, even if it is built without run-time packages:
dac120, unidac120, rtl, dbrtl, vcl, vcldb.
You can find detailed information about it in the "Deployment" topic of UniDAC Help.
In order to solve the problem you should use non-trial edition.
