 Creating database
 ===================

 openstreetmap
 
 You may create it with your preferable client or run next (linux) command:
 
-$ mysqladmin -u <uid> -p create openstreetmap
+$ createdb openstreetmap
 
-(change <uid> with appropriate username of administrative user eg. root )

-Creating user, password, and access rights
-============================================
-
-$ mysql -u <uid> -p

-Creating functions
-====================
+Creating functions for PgSQL
+==============================
 
 Run this command in the db/functions directory:
 
-$ make
-
-The above command should work for linux and most other Unix systems
-that use ELF shared objects. For MacOS X you will need to do:
+$ make libpgosm.so
 
-$ make libquadtile.dylib
+You might also need to install:
+- postgresql development libraries:    $ sudo apt-get install postgresql-server-dev-8.3
+- ruby development libraries:          $ sudo apt-get install ruby1.8-dev
+for build to succeed.
 
-Make sure the db/functions directory is on the MySQL server's library
-path and restart the MySQL server. On linux the easiest way to do this
-is to create /etc/ld.so.conf.d/osm.conf and place the path to the
-db/functions directory in it and then run the following command as root:
+Now create the function as follows:
 
-$ ldconfig
+$ psql openstreetmap
+(This may need authentication or a -u <dbowneruid>)
 
-Now create the functions as follows:
-
-$ mysql -u <uid> -p openstreetmap
-
-(change <uid> with appropriate username of administrative user eg. root )
-
-> create function tile_for_point returns integer soname 'libquadtile.so';
-> exit

-or, for MacOS X:
-
-> create function tile_for_point returns integer soname 'libquadtile.dylib';
-> exit
