This is an interface to the PostgreSQL database //! server. This module is independent of external libraries. //! Note that you @b{do not@} need to have a //! PostgreSQL server running on your host to use this module: you can //! connect to the database over a TCP/IP socket. //! //! This module replaces the functionality of the older @[Sql.postgres] //! and @[Postgres.postgres] modules. //! //! This module supports the following features: //! //! - PostgreSQL network protocol version 3, authentication methods //! currently supported are: cleartext and MD5 (recommended). //! //! - Streaming queries which do not buffer the whole resulset in memory. //! //! - Automatic binary transfers to and from the database for most common //! datatypes (amongst others: integer, text and bytea types). //! //! - SQL-injection protection by allowing just one statement per query //! and ignoring anything after the first (unquoted) semicolon in the query. //! //! - COPY support for streaming up- and download. //! //! - Accurate error messages. //! //! - Automatic precompilation of complex queries (session cache). //! //! - Multiple simultaneous queries on the same database connection. //! //! - Cancelling of long running queries by force or by timeout. //! //! - Event driven NOTIFY. //! //! - SSL encrypted connections (optional or forced). //! //! Refer to the PostgreSQL documentation for further details. //! //! @note //! Multiple simultaneous queries on the same database connection is a //! feature that none of the other database drivers for Pike support. //!
