How does PostGIS store data types?

Does PostGIS store its data types using the WKT binary encoding? Or does it use its own custom binary format? Where can I find more information on how the storage layer works in the PostGIS library?

Solution

  • It stores data in its own internal format, which is neither EWKT nor EWKB. To learn details, you have to read the source.
