Estou usando a funcao reverse em C --
http://blog.frosties.org/post/2007/08/28/Fonction-reverse-C-avec-PostgreSQL
e estou adicionando a funcao char *replace(const char *s, const char *old,
const char *new)
Acrescentei char * str;
str_in = PG_GETARG_VARCHAR_P_COPY(0);
len = (int) (VARSIZE(str_in) - VARHDRSZ);
str_out = (VarChar *)palloc(VARSIZE(str_in));
SET_VARSIZE(str_out, VARSIZE(str_in));
pg_verifymbstr(VARDATA(str_in), len, false);
--Aqui acrescentei
str =(char *)malloc(sizeof(len));
strncpy(str ,VARDATA(str_in), len );
str = replace(str, "0A12","RRJA");
strncpy(VARDATA(str_in),str, len);
Qdo retorna a função retorna falta caracters ? Tem algum jeito de fazer
VarChar receber o char * e vice versa ?
