Обсуждение: schema name in the SQL statement.

My db has one schema. In fact I deleted the default "public" and created
my own: "schema_1".
In my SQL query I have to explicitly specify schema name:
"select my_colomn from schema_1.table_name;"
Can't schema be specified as default value during connection, or can I
set the schema before I send the query?

You can change the database so that everybody connecting to it will use
that schema:
ALTER DATABASE your_db SET search_path = 'schema_1';

You can do that per-user, too:
ALTER DATABASE username SET search_path = 'schema_1';

You can also change it in the application, by sending
SET search_path TO 'schema_1';

There are other options too, but that should suffice.

After the connection is established, set the search_path to be your
schema:  "set search_path to schema_1;"

At that point you can use unqualified relation references again:  "select my_colomn from table_name;"
