PostGIS is a geometric layer over a PostgreSQL Object-Relational Database Management System (ORDBMS) that provides geometry and Spatial Reference System (SRS) handling. The PostGIS reader/writer module enables FME to read geometric PostGIS data as well as underlying attribute data stored in PostgreSQL.
The PostGIS reader/writer is specifically designed to handle the geometric and SRS portions of the data. When reading attribute-only tables from PostgreSQL, the PostgreSQL reader/writer should be used instead. The PostGIS reader/writer communicates directly with the PostgreSQL libpq interface for maximum throughput.
This chapter assumes familiarity with PostGIS and PostgreSQL, the attribute and geometry types supported, and its indexing mechanisms.
