Is it possible to call a language 'C' function from a PL/pgSQL function. I have the following code:
// file myfunc.c
#include "postgres.h"
text* myfunc();
text* myfunc()
{
text* ch;
*ch = '1,2';
return ch;
}
// C file ends here
create function myfunc as
'myfunc.so' langauge 'c';
create function test() returns text as '
declare
at text;
begin
at := myfunc();
return at;
end;
' language 'plpgsql';
The above when executed gives pqReadData()-- backend closed the channel unexpectedly.
