Yes, it is possible. Run installation_package.exe with /SILENT or /VERYSILENT command line parameter. When /SILENT is used the wizard and the background window are not displayed but the installation progress window is.

What PostgreSQL server version is supported by your software?
PostgreSQL Maestro can be used with all the PostgreSQL server versions starting from 7.3.
Does PostgreSQL Maestro support Change Column Types feature implemented in PostgreSQL 8.0?
Yes, it does. PostgreSQL Maestro supports the majority of features implemented in the latest versions of PostgreSQL.
Does PostgreSQL Maestro support the latest server version objects (e.g. tablespaces) management?
Most of objects implemented in PostgreSQL latest versions are supported by PostgreSQL Maestro.
Do I need any additional drivers for operating the database server?
Connection is established via TCP/IP network protocol. No additional drivers are required to communicate with the database server.
What kind of privileges can be applied to table users?
Table users may have SELECT, INSERT, UPDATE, DELETE, RULE, REFERENCES, TRIGGER privileges. They are managed within the Permissions tab of the table editor or within the user editor.
What is about data security during the server connections with your product?
With connection to intermediate SSH server (when all PostgreSQL commands are forwarded through the secure tunnel) support implemented, PostgreSQL Maestro is an attractive variant for those who consider security seriously.
I want to connect to the server via SSH tunnel and I have a public-private key pair that works fine with PuTTY. However when I test the connection, I get an error message "Key is broken".
PuTTY uses its own format to store private keys while our products support private keys stored either in OpenSSH or ssh.com formats. To convert keys from one format to another, use the PuTTYgen utility that can be freely downloaded from the PuTTY website.
Are there any graphical tools for building and executing queries implemented?
PostgreSQL Maestro provides two powerful tools which allow you either to edit query text directly with syntax highlighting and code completion or to build a query diagram visually selecting tables and fields, setting links between tables, etc.
What is the function of Generate Database Report? Does the report include data?
Generate Database Report Wizard allows you to print definitions of the database objects. To run the wizard, select the Tools | Generate Database Report main menu item. The wizard helps you to print all the database object or specify the Categories for printing according to the selected object type. The report does not include database data.
Is code completion implemented in the SQL Editor?
The Editor area is provided for working with the text of the query. For your convenience code completion is enabled. You can activate the completion list by pressing the Ctrl+Space key combination.
I cannot edit the SQL definition using the SQL tab? Why?
The reason is that you are trying to edit SQL definition within the SQL tab of the object editor. Bear in mind that this text is read-only. If you want to modify the object definition, use SQL Editor or SQL Script Editor. You can find the detailed information in the Manual
What is the difference between Object Manager and Object Browser?
Both Object Manager
and Object Browser
are tools for operating on database objects designed as extensions of the Database Explorer. PostgreSQL Maestro provides such operations as multiple selecting of objects (for copying, dropping, etc.) and the ability of using drag-and-drop operations between Object Manager, Object Browser and Database Explorer as well as between instances of the Object Manager or Object Browser. Unlike Object Manager Object Browser represents objects as a grid with according possibilities (sorting, grouping, and filtering).
Is it possible to execute more than one query using SQL Editor?
SQL Editor provides you with an ability to execute several queries simultaneously. Each query is executed in a separate thread, so all PostgreSQL Maestro features remain available and there is no need to wait for your complex query to be completed.
