PgVectorEmbeddingStore(NpgsqlDataSource, bool, string)

Initializes a new instance of the PgVectorEmbeddingStore class using the specified Npgsql.NpgsqlDataSource.

public PgVectorEmbeddingStore(NpgsqlDataSource dataSource, bool ownsDataSource = false, string schema = "public")

Parameters

dataSource NpgsqlDataSource

The Npgsql.NpgsqlDataSource used to obtain pooled connections to the PostgreSQL service. The data source must target a database where the vector extension is available.

Exceptions

ArgumentNullException

Thrown if dataSource is null.

Parameters

connectionString string

A standard Npgsql connection string pointing at the target PostgreSQL database, for example Host=localhost;Username=postgres;Password=secret;Database=vectors.

schema string

The PostgreSQL schema that holds the collection tables. Defaults to public when null or empty. The schema is created on demand when a collection is created.
