If the type is text and you have no idea how long it will be have ecpg/libpq
allocate a buffer for you by using a pointer set to NULL as the variable:
exec sql char *val = NULL;
/* Use an indicator here if you allow the field to be a DB NULL */
exec sql
select text_field into :val
from table
where condition;
/* Check sqlca.sqlcode here */
/* val will now contain the address of an area allocated by ecpg
* holding the contents of the DB field. You can use it and then
* pass val to free() after you're done with it
*/
(do something with val)
/* Clean up */
free(val);
/* Live happily ever after */
