 ST_AsGML is not kiddie proof (at least not on windows anyway).

 This is testing on:

 {{{
 POSTGIS="2.1.0SVN r11349" GEOS="3.4.0dev-CAPI-1.8.0 r0" PROJ="Rel. 4.8.0,
 6 March 2012" GDAL="GDAL 1.10.0, released 2013/04/24" LIBXML="2.7.8"
 LIBJSON="UNKNOWN" RASTER PostgreSQL 9.2.4, compiled by Visual C++ build
 1600, 32-bit
 }}}


 Garden monkey script can crash it with a geography point something like
 this:

 {{{

 SELECT ST_AsGML(2, geography(ST_Point(-1,20)),5,5
   , 'monkey', 'monkey' );
 }}}


 Though:


 {{{
 -- this doesn't crash --
 SELECT ST_AsGML(2, ST_Point(-1,20),5,5, 'monkey', 'monkey' );

 and outputs:
 <monkey:Point><monkey:coordinates>-1,20</monkey:coordinates></monkey:Point>
 }}}


 nor does not specifying a schema

 {{{
 SELECT ST_AsGML(2, geography(ST_Point(-1,20)),5,5 );
 }}}
