PostGIS layers are stored in a PostgreSQL database. The advantages of PostGIS are the spatial indexing, filtering and query capabilities it provides. Using PostGIS, vector functions such as select and identify work more accurately than with OGR layers in QGIS.
What kind of shapefile is compatible with QGIS?
For that reason, if you create a new shapefile with QGIS, two different projection files are created. A .prj file with limited projection parameters, compatible with ESRI software, and a .qpj file, providing the complete parameters of the used CRS. Whenever QGIS finds a .qpj file, it will be used instead of the .prj.
Which is the best vector data format for QGIS?
QGIS uses the OGR library to read and write vector data formats including ESRI Shapefiles, MapInfo, Microstation file formats and many more. GRASS vector, PostGIS, MSSQL Spatial and Oracle Spatial support is supplied by native QGIS data providers. Vector data can also be loaded in read mode from zip and gzip archives into QGIS.
Can you use spit to upload shapefiles to PostGIS?
You can use SPIT for uploading ESRI shapefiles to PostGIS. Once you’ve added the SPIT plugin via the Plugin Manager, look for this button: Clicking on it or selecting Database –> Spit –> Import Shapefiles to PostgreSQL from the menu will give you the SPIT dialog:
How to import a PostGIS table in Windows?

Is there a way to load neighborhoods into QGIS?
I fixed this by running the QGIS tool called ‘Multiparts to Singleparts’ on the neighborhoods file. It’s located in QGIS under Vector > Geometry Tools. Once fixed, both files should load into the database with Spit. Check the DB Manager again, and both files should be visible.
How is the shapefile saved in PostGIS database?
When the Shapefile is saved after modification in QGIS by default the file is also saved in PostGIS database with the new and changed attributes it has before.
