does "linq connect for postgresql" supports array type fields;

At the moment, it is only possible to retrieve array type values as strings. We will analyze the possibility of supporting array types, and post here when our investigation is completed.

when i see pgsqlArray structure, i thouhgth that, i can't do it.

It is possible to work with PostgreSQL arrays via the general ADO.NET components, like PgSqlDataReader and PgSqlCommand, and the PgSqlArray structure:

However, within the LinqConnect ORM it is only possible to read PostgreSQL arrays as strings at the moment. For example, you can only map int[] to System.String in the model, and get the corresponding entity property as a string.

Please tell us if you encounter any problems with PgSqlArray, or have any additional questions about the PostgreSQL arrays support in LinqConnect/dotConnect for PostgreSQL.
