 Data from PostgreSQL can be migrated to {{ ydb-short-name }} using utilities such as [pg_dump](https://www.postgresql.org/docs/current/app-pgdump.html), [psql](https://www.postgresql.org/docs/current/app-psql.html), and [{{ ydb-short-name }} CLI](../reference/ydb-cli/index.md). The [pg_dump](https://www.postgresql.org/docs/current/app-pgdump.html) and [psql](https://www.postgresql.org/docs/current/app-psql.html) utilities are installed with PostgreSQL. [{{ ydb-short-name }} CLI](../reference/ydb-cli/index.md) is {{ ydb-short-name }}'s command-line client, which is [installed separately](../reference/ydb-cli/install.md).
