 Dear all

 Since none of the functions

 {{{
 void postgis_initialize_cache(FunctionCallInfo fcinfo)
 const char *postgis_spatial_ref_sys()
 }}}

 defined in the file lwgeom_pg.c are exported, could you please instruct
 how to solve this issue when using call_function2 for calling the PostGIS
 external function transform(PG_FUNCTION_ARGS)?

 If this help, here is a trace to follow the function calls
