FAQ
Why won't SPIT connect to Postgres?

Question:

I've installed the last version of PostgreSQL (8.0.2) and when I try to use it by shell with "psql testdb" everything works... so I'm sure that installation is correct... when I try to use SPIT plugin of QGIS 0.6 to import shape file, I always get an error message: Connection failed - check settings and try again". I'm new user of PostgreSQL, could someone tell me how to configure each parameter of the server connection, please?

How do I create and use a PostGIS view?
{mos_sb_discuss:3}QGIS depends on the OGC implementation of the geometry_columns table to determine if a table is spatially enabled (i.e. has a geometry column). When creating a view, an entry must be created in the geometry _columns table in order for QGIS to recognize it.

What is the full path to my QGIS install?
{mos_sb_discuss:2}What is the full path to my QGIS install? The full path to your QGIS install may be needed when compiling external plugins or manually installing custom icon themes. The path depends on how you built and/or installed QGIS.
  1. If you configure QGIS using ./configure with no options, the default path will be /usr/local
  2. If you specify --prefix= when configuring QGIS, your path will be what you specified. For example, using ./configure --prefix=/opt/myapps means that the full path to the install will be /opt/myapps
  3. If you installed from an rpm, the full path will be /usr
You can determine the prefix for a QGIS install using the qgis_config. The qgis_config tool is built and installed along with QGIS and can provide the following information:
 
Usage:
   qgis_config OPTION...
 
Options:
   --prefix              print the prefix used by qgis
   --bindir              print destination of executable(s)
   --cflags              print the compiler flags that are necessary to
                         compile a plug-inshow location of C++ header files
   --libs                print the linker flags that are necessary to link a
                         plug-in
   --plugindir           print the path where the plugins are installed
   --major_version       print major version of qgis
   --minor_version       print minor version of qgis
   --micro_version       print micro version of qgis
   --extra_version       print extra version of qgis
   --help                show this help, then exit
 
Is there a way to convert shapefiles to PostGIS?
{mos_sb_discuss:3}Yes, use the SPIT plugin in QGIS or the SPIT standalone binary. SPIT stands for Shapefile to PostGIS Import Tool. SPIT allows you to specify multiple shapefiles and import them into your PostgreSQL/PostGIS database.

SPIT is part of the QGIS core and is built automatically when QGIS is configured with PostgreSQL support.
