PostgreSQL Plugin is a plugin for the 4th Dimension programming language that allows easy connectivity to a PostgreSQL database.
PostgreSQL is a popular open source database platform with connectivity options for many programming languages such as PHP, Perl, Python, TCL, C, Java etc. This means you can easily access your database from a variety of applications written in a variety of programming languages.
The plugin provides features such as rowsets and prepared SQL statements. Rowsets are much like a selection of records in 4D, making it easy for you to browse through the result of a query. Prepared SQL statements make it easy for you to construct valid SQL statements without having to worry about the proper use of quotes.
