while i'm adding a geometry column in postgis by using AddGeometryColumn then the error is

no function matches the given name and argument types. you might need to add explicit type casts

Please Explain clearly

i think because of these error arise from lack of postgis extension of postgres or not proper installation and its dependencies.

you can take more info here about proper installation.

sudo apt-get install pgadmin3 postgresql-9.1-postgis

i hope it helps you...

If PostGIS is properly installed, is the schema you installed the PostGIS functions to in your search path? You can check by using

SHOW search_path;

By default the PostGIS functions are installed in the public schema, so if public's in your search path and you've either installed the PostGIS extension for PostGIS or run the old sql install script then you're probably not providing the correct arguments to AddGeometryColumn. Did you use single quotes around the schema, table, and column names? Did you leave the quotes off when supplying the SRID and dimension arguments?
