A modern C++ API to PostgreSQL that simplifies working with PostgreSQL in C++.

This is a Tcl interface to PostgreSQL, which is itself written entirely in Tcl, and does not rely on libpq. It is highly but not entirely compatible with other Tcl interfaces, although it is slower.

This is a project to evolve and upgrade libpgtcl, the Tcl client interface to PostgreSQL. Application writers will be able to interface to PostgreSQL from Tcl using this interface.

PostgreSQL Tcl Interface Next-Generation (pgtcl-ng) is a loadable Tcl/Tk module for accessing PostgreSQL databases. It extends the pre-8.0 libpgtcl from an early Pgtcl release and from the companion project pgintcl.

PostgresClientKit provides a friendly Swift API for operating against a PostgreSQL database.

• Doesn't require libpq
• Developer-friendly API using modern Swift
• Safe conversion between Postgres and Swift types
• Memory efficient
• SSL/TLS support

PostgresDAC is a component suite for direct access to PostgreSQL servers from Borland Delphi and C++ Builder applications

PostgreSQL Data Access Components (PgDAC) is a library of components that provides native connectivity to PostgreSQL from Delphi, C++Builder, Lazarus (and Free Pascal) on Windows, Mac OS X, iOS, Linux, and FreeBSD for both 32-bit and 64-bit platforms.

PgDAC is designed to help programmers develop really lightweight, faster and cleaner PostgreSQL database applications without deploying any additional libraries.

PgDAC works directly through TCP/IP protocol and does not use the PostgreSQL client library. As data is transferred from socket to storage without additional buffers, the PgDAC performance is maintained on the highest level.

Key Features:

• Rad Studio 10 Seattle support
• Direct access to server data. No need to install other data provider layers
• Full support of the latest versions of PostgreSQL Server and all PostgreSQL Server data types -64-bit development support
• Mac OS X and iOS are supported
• VCL/LCL and FireMonkey compatible
• Direct access to server data without using client library
• Custom PostgreSQL data types to Delphi field types mapping
• Disconnected Model with automatic connection control for working with data offline
• Local Failover for detecting connection loss and implicitly reexecuting certain operations
• All types of local sorting and filtering, including by calculated and lookup fields
• Automatic data updating with TPgQuery, TPgTable, and TPgStoredProc components
• Unicode and national charset support
• Supports many PostgreSQL-specific features, such as notifications, notices, and sequences

postgresql-kit is a set of frameworks, tools, applications and examples for deploying the PostgreSQL database on Mac OS X and iOS platforms.

On the server-side, it provides an embedded server framework which allows you to put a postgresql database right in your Cocoa application. On the client-side, it helps you interact and use all the features of libpq, including converting data seemlessly between Foundation objects and Postgresql data types.

Sample applications for the Macintosh and iOS devices is included in the project, which is licensed with the Apache open-source license.

PostgreSQL Native Provider (PGNP) is an OLEDB Provider for PostgreSQL database.

The provider features support for Linked Servers, replication, DTS, SSIS and more. It can be used from 32-bit and 64-bit Windows applications both native and .NET.

This is PostgreSQL OLE DB Provider project. OLE DB is the default ADO driver technology, and is used by many programs.

Native PostgreSQL driver for LibreOffice and Apache OpenOffice. It is faster, seamlessly integrated and there is no need to install and setup a JDBC or ODBC driver separately. Compatible with PostgreSQL version 8.4 and later.
