Hey,
Thanks for your request!

Unfortunately, the data you provided is not enough to reproduce the issue.
Please clarify which version of PostgreSQL do you use?

Also, please send us a small sample that uses UniDAC and demonstrates incorrect behavior, as well as DDL scripts to create and fill-in database objects.


You can submit it via the form on our website: https://devart.com/company/contactform.html

Thank you for choosing our products! Do not hesitate to ask if you have any other questions. Have a nice day.

Hi Christian,
"An existing connection was forcibly closed by the remote host" means that the server closed the connection.
The reason could be:
1) Sending incorrect data to the server
2) Network problems
3) All system resources have been used
4) Application error

Please note, that without a sample that reproduces the issue we cannot name its cause.

Hi Christian,
Thanks for contacting us!

Could you please update to the latest UniDAC 9.3.0 and see if the issue is reproduced?

You can download the latest version from our website via the following link: https://www.devart.com/unidac/download.html

Hi Jorge,
Thanks for contacting Devart!
Please try to do the following steps:

-Close all applications or services using our driver and uninstall it;
-During the uninstaller program, select the option to remove driver activation information;
-Make sure the driver was successfully uninstalled. For this go to the folder with the previously installed driver and check that it is empty. Delete this folder if it exists and restart your computer;
-Run the driver installer as administrator;
-Activate the driver during the installer - this step is very important;
Please let us know the results!

Please be informed, that the example for Fast Report FMX works for both x86 and x64 bit FMX applications.
The example demonstrates the main functionality for working with components, and not all of their capabilities.
In case if you still have questions after studying the example, please feel free to contact us any time.

After installing UniDAC using the link provided in the previous answer, the demo projects will be installed in the folder.


"c:\Users\%UserName%\Documents\Devart\UniDAC for %IDEVersion%\Demos\
where %UserName% is the user name for which UniDAC is installed,

Among these projects, you can also find an example of how UniDAC works with Fast Report FMX, as well as installation packages for the necessary components.


You can see the components you are interested in the folder

"c:\Users\%UserName%\Documents\Devart\UniDAC for %IDEVersion%\Demos\ThirdParty\FastReport\FMX"

Hi Wolfgang,
Thanks for your request!

The TPgLargeObject class is not designed to work with the type bytea, but rather to work with the type PostgreSQL large objects.
The bytea type is not equivalent to PostgreSQL large object.
With the bytea type you can work as with TBlobField.

You can find more information about the TPgLargeObject class at the following link:
https://docs.devart.com/pgdac/devart.pg ... object.htm

You can find more info about PostgreSQL large objects at the following link:
https://www.postgresql.org/docs/14/largeobjects.html

An example of how the TPgLargeObject class works with PostgreSQL large objects can be found at the link:
https://docs.devart.com/pgdac/work_large_objects.htm

More info about the bytea type you can find at the provided link:
