SpatiaLite

​SpatiaLite is a relatively new GIS file format based on ​SQLite, which uses a single file to store multiple layers and data tables. It is an alternative format to ESRI Shapefiles, which have several legacy issues (such as storage types and lengths of column names, etc.)

Exporting from PostGIS to SpatiaLite

Use ​ogr2ogr built with ​SpatiaLite options.

To create the SpatiaLite file export the first layer:

$ ogr2ogr -f SQLite -dsco SPATIALITE=yes myfile.sqlite PG:"dbname=mydb user=myuser password=mypass" myschema.mytable

And for additional layer/tables:

$ ogr2ogr -f SQLite -update myfile.sqlite b PG:"dbname=mydb user=myuser password=mypass" myschema.my2ndtable
