PostgreSQL ODBC Driver
PostgreSQL ODBC Driver is a high-performance connectivity solution designed to facilitate accessing PostgreSQL databases from applications compatible with ODBC protocol, including Windows 32-bit and 64-bit versions, macOS, and Linux platforms. It supports standard API functions and data types standardized within ODBC emulation.

Clicking Add will bring up a dialog box entitled Create a New Data Source and allow you to select one or more sources to use as data sources in ODBC Administrator.
ODBC Compatibility:
Our ODBC driver allows your applications to directly access PostgreSQL for real-time analytics, removing the need for PostgreSQL libraries or clients and improving application performance while eliminating deployment issues.
This ODBC Driver supports the full suite of standard ODBC API functions, giving you confidence that it will work with your application. Furthermore, it’s compatible with 32-bit and 64-bit Windows applications, Linux, Macintosh OSX, or Unix (including Solaris).
Installation of the PostgreSQL ODBC Driver is straightforward: simply follow the on-screen instructions to complete installation and then click Finish when complete. Afterward, launch ODBC Data Source Administrator; on the System DSN tab select Add; choose PostgreSQL Unicode (x64); click Finish then.
Connecting an ODBC application to a database enables it to read and write data to any table in it, using SQL queries such as viewing or updating table rows or using stored procedures and triggers as necessary.
Connect to PostgreSQL databases from the command line using the psqlODBC utility provided by its distribution and use Windows to test and configure your ODBC driver.
ODBC Data Types:
ODBC data types provide applications with an interface between database servers from different manufacturers and applications. Each ODBC data type specifies how much physical storage is set aside for it and in what form. So, each DBMS data type corresponds with an associated ODBC data type – for instance, DB2’s Historian_Data is associated with SQL_HIST_DATA in ODBC.
Each ODBC data type features a set of functions that can be called to perform operations on it. These ODBC functions can be written in any programming language and made available to any application that supports ODBC; typically these include the SELECT statement and UPDATE statement.
The ODBC API also provides core functions that facilitate additional functionality, including row versioning – an option that allows applications to quickly detect when a specific column has changed and therefore speeds up updates.
ODBC not only facilitates data access but it is also the means for Java programs to access a PostgreSQL database through ODBC, using the psqlODBC program included with PostgreSQL server distributions. This program implements both standard ODBC functionality as well as extensions tailored specifically for the PostgreSQL database; its Java implementation follows JDBC specification with reasonable performance results; while Devart PostgreSQL ODBC Driver fully supports all features offered by the psqlODBC program.
ODBC Functions:
ODBC API reference documentation offers general details about its functions. Below is a table containing TimesTen-specific options you can use to customize ODBC functions’ behavior.
Setting various descriptor fields that govern aspects of environments, connections, statements, and cursors attributes is also possible here; setting SQL_TRUE for the statement attribute at application startup may improve performance when running large volumes of statements against the database server.
Return a list of statistics about tables and their indexes stored in a data source. This function can significantly enhance performance when selecting rows from large-capacity tables.
Allows a query to specify the name of a table or schema instead of its physical file location, thus eliminating the need for opening and closing files whenever performing database operations such as SELECT or UPDATE.
Enabling this option allows the ODBC Driver to bypass Fetch Buffer Size when retrieving Ref Cursor parameters, potentially improving performance for procedures with many parameter types and frequent execution.
Allows applications to access more comprehensive diagnostic information for an ODBC Driver. This optional parameter provides two pointers to a data structure containing native error message, record number, SQLState code, and trace number information for errors found within specific status records. Please be aware that these pointers must correspond with information returned by SQLGetDiagRec() function of ODBC.
ODBC Security:
The ODBC driver supports the SCRAM-SHA-256-PLUS authentication method to establish secure connections to PostgreSQL databases. This feature encrypts passwords sent from clients directly to the ODBC server from client applications and allows program-adopted security where database updates occur through stored procedures rather than desktop application commands.
The parsing code used to identify table names from an INSERT INTO statement did not properly handle “?”-style strings, sometimes reporting a NULL value instead of an error message. This has now been addressed.
Once upon a time, the driver would send a request to the server to ascertain client_encoding settings; now this query has been eliminated as all supported server versions now include this information as part of connection handshake allowing an ODBC client to connect over higher latency links without incurring additional network traffic.
The ODBC driver for PostgreSQL is a flexible data connector that offers seamless connectivity to on-premises and cloud PostgreSQL databases such as RDS, Amazon Aurora, and Enterprise DB from all major platforms and applications like Microsoft Power BI, SAP BusinessObjects, Oracle ETL Informatica SAS Cognos. It supports advanced data conversion mechanisms as well as compatibility with the latest PostgreSQL versions as well as fast parallel bulk updates – and provides SSL/SSH-protected communication to reduce deployment and management costs!
