against PostgreSQL versions &min_postgres_version; or higher. Earlier

For GEOS functionality, when you install PostgresSQL you may need to

This is a workaround for bogus C++ exceptions interaction with older

development tools. If you experience weird problems (backend

unexpectedly closed or similar things) try this trick. This will require

recompiling your PostgreSQL from scratch, of course.

By default PostGIS will try to detect gettext support and compile with it, however if you run into incompatibility issues that

cause breakage of loader, you can disable it entirely with this command. Refer to ticket <ulink url="http://trac.osgeo.org/postgis/ticket/748">http://trac.osgeo.org/postgis/ticket/748</ulink> for an example issue solved by configuring with this.

NOTE: that you aren't missing much by turning this off. This is used for international help/label support for the GUI loader which is not yet documented

As of PostGIS v1.4.0, all the functions have comments generated from the

documentation. If you wish to install these comments into your spatial

databases later, run the command which requires docbook. The postgis_comments.sql and other
|
|
package comments files raster_comments.sql, topology_comments.sql are
|
|
also packaged in the tar.gz distribution in the doc folder so no need to make comments

if installing from the tar ball.

The PostGIS extensions which is usable for PostgreSQL 9.1+, can be built by cding into the extension folders and doing a make install.

This will be an automated process in the future when PostGIS is compiled against a 9.1 build and fully integrated int ot he build process.

|
|
<para>Building the comments is not necessary if you are building from a release tar ball since these are packaged pre-built with the tar ball already.</para>
|

<para>If you are building against PostgreSQL 9.1, the extensions should automatically build as part of the make install process. You can if needed build from the extensions

You need to copy the following files from the extensions folder into the <filename>PostgreSQL / share / extension</filename> folder

<para>If you have the extension installed in the you are querying, you'll see mention in the <varname>installed_version</varname> column.
|
|
If you get no records back, it means you don't have postgis extensions installed on the server at all. PgAdmin III 1.4+ will also provide this information
|
|
in the <varname>extensions</varname> section of the database browser tree and will even allow upgrade by right-clicking.</para>
|

<para>If you have the extensions available, you can install postgis extension in your database of choice by either using pgAdmin extension interface or running these sql commands:</para>

All your custom records with invalid SRIDs will be retained,
